remove a carriage return or newline from JavaScript array

Question

I am working with an array populated by a text file and parsed with a regex. The first element in my array appears with either \\r or \\n like so:

" This is the first element"

This only occurs on the first element. How would I go about removing this hidden character? I have tried map with replace('\\r', ''), and other iterations of replace with no luck. Thanks for any help.

Tried adding as a comment but a previously answered question should get you going in the right direction.

How to remove all line breaks from a string?

Answer 2

There isn't much more than replace, really. To remove all those characters you can use:

str.replace('\r', '').replace('\n', '');

Mind you have to re-assign the result to the string as it is not an in-place replace but it creates a copy of the string:

str = str.replace('\r', '').replace('\n', '');

I would discourage using a regular expression for such a simple task. It would be overkill and take much more processing time. I admit it's a tiny fraction of time, but in a massive loop it may make a difference.
