Iterating through a string or an array in js.

Question

How to use a for loop for iterating through an array or a string in js.

Answer 1

The way I do it is by splitting the string and then use for each.

Example:
let myStr = "ABCD".split('');

Object.values(myStr).forEach((v)=>{
console.log(v);
});

Answer 2

SoundInfinity can't we use for loop like we do in python

Answer 3

Yash yes you can use for loops to iterate through strings and array, just like in python. How have you tried iterating ? Post your attempt here.

Answer 6

Yash I did it on my own, so I am really not sure, if it also could be done just like in Python. Also, my previous code wasn't 100% correct, but I fixed it.

Answer 7

Yash can you show me your attempt first ? I just want to see how you tried it, so I can tell you where your mistake is.

Answer 8

Yash read this, it contains different ways to iterate throught an array (including almost-python syntax for the first one, which is what I was talking about):

And by the way, even if you are a beginner, it does not mean you can't use search engines. The link I shared was the first result I got after searching on google writing exactly what you asked, so please try to search next time, especially for simple things like these. Thanks for understanding!

Answer 9

Can't you just use for of?

const str = 'Yea!'
for (let item of str) {
document.write(item + ' | ')
}
