Lecture 153:- Iterating over array using for in

It is generally not recommended to use a for...in loop to iterate over an array in JavaScript, as this loop is meant to be used for iterating over an object's properties, not an array's elements.

Instead, you can use a for loop or a for...of loop to iterate over an array in JavaScript. Here's an example of how to use a for...of loop to iterate over an array:

javascriptCopy code

const array = [1, 2, 3, 4, 5]; for (const element of array) {  console.log(element); }

This will log each element of the array to the console. If you need to get the index of each element, you can use the entries() method on the array to get an iterator that returns the index and value of each element, and then use a for...of loop to iterate over the iterator:

javascriptCopy code

const array = [1, 2, 3, 4, 5]; for (const [index, element] of array.entries()) {  console.log(index, element); }

This will log the index and value of each element to the console.
