+155. ### What are the string methods that accept Regular expression

+     There are six string methods: search(), replace(), replaceAll(), match(), matchAll(), and split().
 
-     Regular Expressions has two string methods: search() and replace().
      The search() method uses an expression to search for a match, and returns the position of the match.

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

+     ```javascript
+     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.
 
      ```javascript
      var msg = "Hello John";
-     var n = msg.replace(/John/i, "Buttler"); // Hello Buttler
+     var n = msg.split(/\s/); // ["Hello", "John"]
