New Post: Understanding control flow syntax in Angular 17 - https://lnkd.in/gKiPnNCH - As software developers, we’re subjected to an ever-changing landscape of tools, best practices, and ways of doing things. Sometimes, when a change is introduced, it’s tempting to stay with old habits. It could be that the old way is more intuitive or easier, but often, it’s just that we don’t want to learn and remember yet another new thing. A good example of this is the new control flow syntax that has been added in Angular 17. The reality is that it’s a huge new feature that offers significant benefits to pretty much any Angular developer. But to learn how to use it, we have to dive into the value of what control flow syntax can do for us. The problem with Angular before control flow syntax One of Angular’s hallmarks — even in the AngularJS days — was that, within its HTML templates, everything could be controlled through HTML tags. This made writing Angular applications intuitive, since if you understood the HTML, you could naturally leverage that skill to understand how Angular worked. This was a good approach for most of the features within Angular. One area where this approach started to break down, however, was in comparatively simple operations like conditional rendering, or even for...of loops that could render multiple items in an array. Even in TypeScript, the language that backs Angular, these operations were far simpler and more intuitive than they ever were in Angular’s HTML templates. For example, in TypeScript, a conditional operation would look like this: if (booleanCondition){ // if true } else { // if false } Whereas in Angular, a similar operation would look like this: <div ngIf="booleanCondition"> true </div> <div ngIf="!booleanCondition"> false </div> The natural flow of “if this, do this; otherwise, do that” is lost. Instead, we have to negate the booleanCondition manually to show something else. Angular does have an option to use something like an else statement, but in my opinion, it’s never been easy to use and is so overly verbose and inflexible that I never actually used it: <div ngIf="booleanCondition; else elseBlock">Condition is true</div> <ng-template #elseBlock>Condition is false</ng-template> Straightaway, the relationship between the if and the else block is not clear. We have the condition written in our ngIf attribute, but it calls out to a different HTML tag. As soon as the page approaches any level of complexity, trying to dig through the HTML to find what is going to be rendered becomes difficult. This is only exacerbated by else...if rendering: <div ngIf="condition; then thenBlock else elseBlock"></div> <ng-template #thenBlock>It's true.</ng-template> <ng-template #elseBlock>It's false.</ng-template> In cases where you want to render something different based on something li

Comparing two different frontend technologies Introduction:There are many types of frontend technologies,but in this article, i will be comparing two popular ones. My case of study will be focusing on JavaScript and Angular. JavaScript: It is a programming language used for creating interactive effects within web browsers. It can be used for both front-end (client-side) and back-end (server-side) development. JavaScript is versatile and can be used with various libraries and frameworks, or standalone. JavaScript is versatile and can be used with any framework or library. It has a straightforward syntax, which makes it relatively easy to learn. Angular: It is a platform and framework for building single-page client applications using HTML and TypeScript. It’s used for creating dynamic web applications and provides a structured way of building them. Angular follows the MVC (Model-View-Controller) architecture, which helps in organizing code.It provides features like two-way data binding, dependency injection. Differences: Purpose: JavaScript is a language used for scripting, whereas Angular is a framework that uses JavaScript (specifically TypeScript) to build applications. Learning Curve: Angular has a steeper learning curve due to its comprehensive framework features and TypeScript usage, whereas JavaScript is more accessible for beginners. Scalability: Angular provides more scalable and maintainable approach for larger applications compared to vanilla JavaScript, which might become harder to manage as projects grow. What makes them better: JavaScript: It’s better in scenarios where simplicity and flexibility are prioritized, such as small scripts or when integrating with various libraries and frameworks. Angular: It excels in building complex, single-page applications (SPAs) where structure, maintainability, and scalability are critical. Angular's features and tools streamline develops and enhances developer productivity in large projects. I am expecting to learn all about frontend in Hng. Feelings about React: I find React to be an exciting and powerful library for building modern web applications. Community and Ecosystem: React has a large and active community, which means extensive documentation, tutorials, and third-party libraries that enhance productivity and solve common development challenges. Learning Curve: While React has a learning curve, once understood, its concepts and patterns provide a solid foundation for scalable and maintainable applications. Conclusion: In summary, JavaScript is foundational and versatile, while Angular is a specialized framework that leverages JavaScript to provide a robust structure for building sophisticated web applications. The choice between them depends on project requirements, team expertise, and scalability needs. https://hng.tech/hire and https://lnkd.in/g8jyj8xd

Angular is a front-end JavaScript framework written on TypeScript. Some of the features of the Angular framework include using data-binding, which is a process that enables users to manipulate web page elements through a web browser and employs dynamic HTML. Angular is focused on a component-based architecture and was developed using Typescript. It combines modern architectural approaches to handle complex web application requirements. It separates the responsibilities and for that the view from the logic. As developers, we can split an application in such a way that it becomes maintainable, testable, and extensible. The idea is to break the application into small testable pieces so that the developer paradigms of “single-responsibility” and “separation of concerns” can be adhered to.  Angular helps with many emerging issues such as creating components, data-binding to the UI/HTML, transforming data against the UI with pipes, offloading “work” to services, communicating with an API, etc. In addition, by using Typescript, Angular has a similar type of safety as could be on other languages like C# or Java. In the following application I deployed, which is an appointment app, I created a model interface to display an object with each data appointment booked and connected the "component.ts" file with the "component.html" to display the list of appointments.   By utilizing the “ngFor” loop directive the list of appointments is displayed. On the list "component.ts", the ngOnInit lifecycle hook method is called when the component is initialized. “This.appointments” property of the Angular component will retrieve the data from the web browser's local storage. If data is found in local storage, it's parsed from JSON format and assigned to "this.appointments". If no data is found, "this.appointments" is initialized as an empty array. I used local storage to retrieve the value associated with the key “appointments”, which is a way to store data on the client side, which means the data will persist even if the user closes the browser and returns to the website later. The overall purpose of this code was to create a form where users can input the title and date of an appointment. When they click the "Add" button, it will trigger the "addAppointment()" method in the component to process and add the new appointment to the application. The [(ngModel)] directives ensure that the values entered by the user are bound to the component's properties for further processing. I also used Bootstrap to style the entire application.     Site Link: https://lnkd.in/d6khVD_3   GitHub Link:   https://lnkd.in/d34vEPyT #angulardeveloper #angulardevelopment #fullstackdeveloper #softwaredeveloper #typescript #webdevelopment #softwareengineering #frontenddeveloper #backenddeveloper #angulardevelopers #fullstackdeveloper #fullstackdevelopment    

Hey Connections, Sharing some core insights into some interesting Angular and UI features - split into 50 days 31/50 - Whats esbuild and why is it so fast? Since Angular v16.1 we can use esbuild as our code bundler. And from Angular v17 it uses esbuild as its bundler by default. But what exactly is esbuild, and why is it so popular? 💡 esbuild is a free and open-source module bundler and minifier for JavaScript and CSS written in Go instead of JS as most bundlers like webpack. 🔹 It supports TypeScript, JSX, tree-shaking, is extensible through plugins, and claims to be "10 to 100 times" faster than other bundlers. [Image : Shows time taken to bundle 10 copies of 3.js which is a huge JS library, by various bundlers] But why is it so fast? There are several reasons. 🔸 It’s written in Go and compiles to native code. 🔹 Most other bundlers are written in JS, but a CLI app is the worst case performance situation for a JIT compiled language. 🔹 While esbuild is busy parsing your JavaScript, Node is busy parsing your bundler's JavaScript. 🔸 Parallelism is used heavily. 🔹 Go is designed from the core for parallelism while JS isn’t. The algorithms inside esbuild are carefully designed to fully saturate all available CPU cores when possible. 🔸 Everything in esbuild is written from scratch. 🔹 esbuild does not use any 3rd party libraries, as it was focused on performance from the beginning, whereas many bundlers use 3rd party libraries. 🔹 For instance, many bundlers use official TS compiler as a parser, which didn’t have performance as a top priority. esbuild has it’s own custom TS parser. 🔸 Memory is used efficiently 🔹 esbuild reuses most of the data from the compilation phases for efficient memory usage. 🔹Another benefit of GO is that it can store things compactly in memory. 💡 All of these factors together provide a significant speedup of multiple orders of magnitude (10x - 100x) ⚡ as compared to commonly used bundlers today.
