How can you create an array in JavaScript?

Short answer: const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2,…

Example code

const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3); const arr1 = [1, 2, 3]; const arr2 = new Array(1, 2, 3);

Real-world example (ShopNest)

ShopNest’s browser cart uses modern JavaScript: fetch APIs with async/await, modules, and clear error handling.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
