How to use RegExp in TypeScript?

To use RegExp in TypeScript, we can use it as we do with JavaScript.

For instance, we write

const trigger = "2";
const regexp = new RegExp("^[1-9]d{0,2}$");
const test = regexp.test(trigger);

to create a new regex with the RegExp constructor that matches any number with 0 to 2 digits.

Then we call test with the trigger string to see if it matches.
