replaceAll search  replaceWith   MDN    quot  a b c  quot  replaceAll               result   quot  a b c  quot       Using RegEx  You MUST use a global RegEx    quot  a b c  quot  replaceAll     g           result   quot  a b c  quot        replaceAll   replaces ALL occurrences of search with replaceWith  It s actually the same as using replace    MDN  with a global regex     merely replaceAll   is a bit more readable in my view      Meaning it ll match all occurrences   Important    if you choose regex   when using a regexp you have to set the global   quot g quot   flag  otherwise  it will throw a TypeError   quot replaceAll must be called with a global RegExp quot
