Check For Mixed Grouping of Characters # 40

Sometimes we want to check for groups of characters using a Regular Expression and to achieve that we use parentheses ().

If you want to find either Penguin or Pumpkin in a string, you can use the following Regular Expression: /P(engu|umpk)in/g

Then check whether the desired string groups are in the test string by using the test() method.

let testStr = "Pumpkin";
let testRegex = /P(engu|umpk)in/;
testRegex.test(testStr);

The test method here would return true.
