JS Reference vs Value Explained! #coding #codingquiz #programming #frontenddev #javascript #array

Показать описание

This JavaScript behavior shocks beginners!
👇
When you assign const arr2 = arr1, you're not creating a new array. You're pointing both arr1 and arr2 to the same memory.
💡 In JavaScript, objects and arrays are assigned by reference, not by value.
Avoid this trap — or your bugs will multiply faster than you think! 🐛🔥

Explanation :
arr1 is an array → arrays are objects in JavaScript.
const arr2 = arr1 doesn’t copy values — it creates a reference to the same memory.

Explanation :
arr1 is an array → arrays are objects in JavaScript.
const arr2 = arr1 doesn’t copy values — it creates a reference to the same memory.
So when arr2.push(3) is called, it's actually pushing to the same array in memory.
