Strip Numbers From a String
const greeting = 'Hello Marcus, welcome in 2020'; const withoutNumbers = greeting.replace(/\d+/g, '') // or (works the same way and is a bit more verbose) const withoutNumbers = greeting.replace(/[0-9]/g, '') // withoutNumbers = 'Hello Marcus, welcome in '
\d RegEx matches any number. The
+ modifier is a flag to match all adjacent numbers. Using
/g finds and replaces all numbers in the string in one go.
Use a Package
I’m the maintainer of the @supercharge/strings package providing convenient string utilities. Stripping numbers from a string are is one of the available functions.
const Str = require('@supercharge/strings') const withoutNumbers = Str('Hello Marcus, welcome in 2020').stripNums().get() // 'Hello Marcus, welcome in '
