How to replace all occurrences of a string

0 votes

I have this string:

"Test abc test test abc test test test abc test test abc"

Doing:

str = str.replace('abc', '');

seems to only remove the first occurrence of abc in the string above.

How can I replace all occurrences of it?

The general pattern is

str.split(search).join(replacement)

This used to be faster in some cases than using replaceAll and a regular expression, but that doesn't seem to be the case anymore in modern browsers.

Conclusion: If you have a performance-critical use case (e.g processing hundreds of strings), use the Regexp method. But for most typical use cases, this is well worth not having to worry about special characters.
