Question

Say I had the following string:

var str = '(1 + foo + 3) / bar';

And I want to replace all strings just with the letter 'x'. I tried:

str = str.replace(/\w/g, 'x');

This results in:

(x + xxx + x) / xxx

Instead, I would like the result to be:

(1 + x + 3) / x

How would I do this? How would I find just the words that don’t have digits and replace the word to a single letter?

Answer 1

Why not just use [a-z]+ instead of \w? (Make sure to add the case-insensetive flag, or use [a-zA-Z] instead)
