ES6 Introduced Major Updates To JavaScript, Making It More Powerful & Easier To Work With...
Let’s Explore Some Key Features That Will Enhance Your Coding Skills!
Let and Const: Say Goodbye to var
ES6 introduced let and const, providing block scope for variables.
let is used for variables that may change, while const is for constants that don’t change.
Let and Const: Say Goodbye to var
let age = 25;
age = 26; // Allowed
const name = 'Alice';
name = 'Bob'; // Error: Assignment to constant variable.
Arrow Functions: Short and Sweet Syntax
Arrow functions provide a concise way to write functions.
And automatically bind the this context from their surrounding scope.
Arrow Functions Syntax
// Traditional functionfunction add(a, b) { return a + b;}// Arrow functionconst add = (a, b) => a + b;
Template Literals: Easier String Interpolation
Template literals use backticks (``) and ${}.
For embedding expressions within strings, making it easier to create multi-line strings and embed variables.
Template Literals: Syntax
const name = 'Alice';const greeting = `Hello, ${name}! Welcome to the ES6 world.`;console.log(greeting); // Output: Hello, Alice!
Destructuring Assignment: Extracting Values Made Easy
Destructuring Allows You To Unpack Values From Arrays Or Properties.
From Objects Into Distinct Variables With A Concise Syntax.
Promises and Async/Await: Simplifying Asynchronous Code
Promises And Async/Await Provide A Cleaner Way To Handle Asynchronous
Operations, Avoiding Callback Hell & Making The Code More Readable.
Promises & Async/Await: Syntax
// Using PromisesfetchData().then(console.log); // Logs 'Data fetched!' after 1 second// Using Async/Await(async () => console.log(await fetchData()))(); // Logs 'Data fetched!' after 1 second
Modules: Organize Your Code Efficiently
ES6 Modules Allow You To Break Your Code Into Separate Files.
And Import/Export Them As Needed, Promoting Better Code Organization And Reusability.
