// **Challenge 17** // Problem Description: // Write a JavaScript function named filterOutOdd that uses the filter() method to filter out odd numbers from an array. // Inputs: // An array of numbers. // Outputs: // An array of numbers without odd numbers. // Hints: // Use the filter() method to create a new array with all elements that pass the test implemented by the provided function. // Solution Approach: // Use the filter() method and provide a callback that checks if the number is even.   function filterOutOdd(nums){     let result = nums.filter( num => num %2 == 0)     return result   } let numbers = [1,2,3,4,5,6,7,8] console.log(filterOutOdd(numbers))  

Hello connection Good Morning everyone Remember these four steps for using loops in JavaScript while loop syntax: Step 1: Starting point; Step 2: Condition/ Logic; Step 3: Output/ console.log(); Step 4:increment/ Decrement For loop syntax: Step 1: Starting point; Step 2: Condition/ Logic ; Step 3 : increment / Decrement  Step 4 : Output/ Console.log;  The Major difference is while loop and for loop is while loop write a code in line line but in for loop write a code in one line only .

9.Write a JavaScript program to combine the numbers of a given array into an array containing all combinations. Use Array.prototype.reduce() combined with Array.prototype.map() to iterate over elements and combine into an array containing all combinations. Solution : const powerset = arr => arr.reduce((a, v) => a.concat(a.map(r => [v].concat(r))), [[]]); console.log(powerset([1, 2])); console.log(powerset([1, 2, 3])); console.log(powerset([1, 2, 3, 4]));

Javascript's Event Loop in a nutshell ⚡️ Let's quickly take a look at what's happening when we're running this code in a browser: ____________________________________________________________ const foo = () => console.log("First"); const bar = () => setTimeout(() => console.log("Second"), 500); const baz = () => console.log("Third"); bar(); foo(); baz(); ____________________________________________________________

Javascript Roadmap ✅️ ================ ✅️ - Variables (let , var , const) - Data types and their methods - operators - Arrays - objects - Functions ===========✅️ - control statement - Template literals - scope in js - Hoisting - spread operator - sets ============✅️ - promises , Async & await - Import and export - Rest operators - constructor functions, inheritance - classes ============✅️ - cookies VS local storage - How js engine works - practice and build projects - Dom manipulatation - closuers

In JavaScript, the fetch function is used to ____ (A: store data, B: retrieve data from a server, C: manipulate the DOM, D: handle errors). Drop your answer in the comments! 🤔💬 #JavaScript #WebDev #TechTrivia #CodingCommunity

#javascript tip : Use console.table for better visibility of data, it shows arrays and objects to the console in tabular form (check attached code snippet).

JavaScript: What’s the difference between var, let and const Var - is function scoped and the original way to assign variables Let and const - are block scoped and the more modern way to assign variables Let can be reassigned while const is a “constant” - read only

// Challenge 12 // Write a JavaScript program to create a clock. // Note: The output will come every second. // Expected Console Output: // "14:37:42" // "14:37:43" //  "14:37:44" // "14:37:45" // "14:37:46" // "14:37:47"   function myclock(){     let dt = new Date();     let hours = ('0' + dt.getHours()).slice(-2);     let minutes = ('0' + dt.getMinutes()).slice(-2);     let seconds = ('0' + dt.getSeconds()).slice(-2);     console.log(`${hours}:${minutes}:${seconds}`); } setInterval(() => {     myclock(); }, 1000);
