Find and Replace with String or RegEx

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

js 
const original = "the quick brown fox"

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

console.log(updated)
results start

This can also be done with a regular expression

TODO : See also : [TODO: Code shorthand span ] 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

js 
const regex = /\d+s/g

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

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

console.log(updated)
results start
