I just want to know the difference between the two codes

var myArr = [ 2, 3, 4, 5, 6];
var total = 0;
 for (let item of myArr) {
     total += item 

for (var i=0;i<myArr.length;i++) {
    total += myArr[i] 

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

Hi @praveen511!

Welcome to the forum!

Both loops do the same thing, it is just written a little differently.

For loops can be used for pretty much anything while for… of loops are good for arrays, strings and other array like objects.
