“.replace is a regular expression replacement method” (@Jay)

I think that’s quite misleading. From what you’ve said one would assume that the replace-method’s first argument is converted to a regular expression implicitly when in fact, if you pass a string, it’s treated as literal text and is not converted to a RegExp object.

Also, just to clarify, /regex/ is the same as RegExp(‘regex’) – which, btw, doesn’t require the new operator.

FTR, JS’s replace function DOES act like replace functions in other languages, just perhaps not the ones you’re expecting it to.

It doesn’t work like str_replace in PHP, but it is very similar to preg_replace.

As long as developers are aware that .replace is a regular expression replacement method, I think it’s pretty straightforward.

It should also be noted that one can create a regular expression using something like:

var regex = new RegExp(‘MooTools’, ‘g’);

And that regular expression can be used in the replace function (first parameter). Which is helpful if you ever want to use the contents of a variable in your replacement:

Don’t forget to escape!
