What are the string methods that accept Regular expression?

There are six string methods: search(), replace(), replaceAll(), match(), matchAll(), and split().

The search() method uses an expression to search for a match, and returns the position of the match.

      var msg = "Hello John";
      var n = msg.search(/John/i); // 6
      

The replace() and replaceAll() methods are used to return a modified string where the pattern is replaced.

      var msg = "ball bat";
      var n1 = msg.replace(/b/i, "c"); // call bat
      var n2 = msg.replaceAll(/b/i, "c"); // call cat
      

The match() and matchAll() methods are used to return the matches when matching a string against a regular expression.

      var msg = "Hello John";
      var n1 = msg.match(/[A-Z]/g); // ["H", "J"]
      var n2 = msg.matchAll(/[A-Z]/g); // this returns an iterator
      

The split() method is used to split a string into an array of substrings, and returns the new array.

      var msg = "Hello John";
      var n = msg.split(/\s/); // ["Hello", "John"]
