replace Function

replace searches a given string for another given substring, and replaces each occurrence with a given replacement string.

replace(string, substring, replacement)

If substring is wrapped in forward slashes, it is treated as a regular expression, using the same pattern syntax as regex. If using a regular expression for the substring argument, the replacement string can incorporate captured strings from the input by using an $n sequence, where n is the index or name of a capture group.

Examples

> replace("1 + 2 + 3", "+", "-")
1 - 2 - 3
 
> replace("hello world", "/w.*d/", "everybody")
hello everybody
