How to get rid of a portion of a string using regex?

To get rid of a portion of a string using regex, you can use the replace method in JavaScript or a similar method in other programming languages.

Here's an example in JavaScript:

1
2
3
4
5

let str = "Hello, World!";
let regex = /Hello, /;
let newStr = str.replace(regex, "");

console.log(newStr); // Output: World!

In this example, the replace method is used with a regex pattern /Hello, / to match and remove the portion "Hello, " from the string "Hello, World!". You can replace the regex pattern with any pattern you want to match and remove from the string.
