Lesson 10 of 20
Modern JavaScript (ES6+)
Use modern syntax for clearer programs.
Introduction
ES6 introduced let, const, arrow functions, template literals, classes and modules. Newer editions continue improving the language.
Modern syntax reduces repetition but still compiles to browser-compatible code when needed.
Key insight
Use modern syntax for clearer programs.
Example
const greet = (name) => `Hello, ${name}!`;
console.log(greet("Asha"));This example shows the core modern javascript (es6+) idea in a small, runnable program.
Real-world example
Modern React and Node.js projects use ES6+ syntax throughout.
