How to globally replace pipe symbol “|” in string

Question

How can I globally replace the | (pipe) symbol in a string? When I try to replace it with \"so|me|str|ing\".replace(/|/g, \'-\'), I get \"-s-

Answer 1

| has special meaning (A|B means "match A or B"), so you need to escape it:

"so|me|str|ing".replace(/\|/g, '-');
