Can replace() be used in a forEach loop?

Question

Hi so assume I have a match() output array where all elements are strings, and i want to replace some of the text inside those strings but using forEach() instead of a regular for loop.

lets suppose the output array is

stringsArray = ["<div>some text here</div>","<div>Some other text here</div>"];

again the code above is the output of a match() of some text. which prints correctly in the console.

let parsedArray = stringsArray.forEach(element => element.replace(/<div>|<\/div>/g,'\n'));

for some reason the code above doesn't work, console.log(parsedArray) comes back undefined.

should i use a regular for loop instead, if so why?

forEach() just iterates through the array. Changes to element are only made to that local copy, and are not returned.

Try map(), which lets you return an altered element:

let parsedArray = stringsArray.map(element => { return element.replace(/<div>|<\/div>/g,'\n') });
