Question

What is regular expression would I use to find the word “oy”? I need it to work in a userscript. Also, I have to make sure it doesn’t remove words that contain “oy”, like “Olive Oyl”.

Answer 1

You need /\boy\b/g.

Explanation:

The \b means word boundary (start or end of a word). The g on the end means to search for more than one occurence (global). Finally, if you want the search to be case insensitive, add an i after the g:

/\boy\b/gi

To remove all “oy” words in a string str, you do:

str.replace(/\boy\b/gi, "");
