digits-only

Returns a string which is ONLY the digits of the argument.

Note:

• A string is ALWAYS returned (never null)
• The argument is coerced to be a string if it's not already
• Coercing a number to a string gives you the result you'd expect
• Coercing an object to string is not the same as producing JSON, so probably doesn't produce anything useful

Install

npm i digits-only

Usage

const digitsOnly = require('digits-only')
let val = digitsOnly('123-345-2341')	// val == '1233452341'
