Find and Replace with String or RegEx

The simplest replacement is substituting one string for another with `.replaceAll()`

Code

const original = "the quick brown fox"

const updated = original.replaceAll('brown', 'green')

console.log(updated)

the quick green fox

This can also be done with a regular expression

TODO: See also: `.replace()` which only does one

This is an example using a regex. You can also use a string. TKTKTK make more examples including ones with functions and strings

const regex = /\d+s/g

const original = "There are 1000s and 1000s of corgis"

const updated = original.replace(regex, 'lots')

console.log(updated)

There are lots and lots of corgis
