ES6 destructuring and defaults

const profile = { name: 'Mostafa', role: 'Developer' };
const { name, role, country = 'BD' } = profile;

const add = (a = 0, b = 0) => a + b;
const summary = `${name} works as ${role} from ${country}`;

Defaults, destructuring, and templates reduce boilerplate fast.

Core features covered

  1. Hoisting behavior awareness.
  2. let and const block scoping.
  3. Default function parameters.
  4. Rest and spread operators.
  5. Arrow functions.
  6. Destructuring assignment.
  7. Promises for async flows.
  8. Class syntax over prototypes.
  9. Enhanced object literals.
  10. Template literals.

Why these features matter together

ES6 is not one feature. It is a compounding readability upgrade. When these features are used consistently, code becomes easier to scan, easier to refactor, and less error-prone in async and state-heavy logic.

Adoption tip
