TypeScript - find text in string

In TypeScript it is possible to find text in string with String search method.

1. Overview

String search method works in following way:

• as first argument takes regular expression
• returns first text occurrance position,
• returns -1 value if nothing found

2. String search method with regular expression example

2.1. With text argument 

const text: string = 'This is my text...';

const position1: number = text.search('is'); // be careful because of regex characters
const position2: number = text.search('\\bis\\b');

console.log(position1); // 2
console.log(position2); // 5

2.2. With object argument example

const text: string = 'This is my text...';
const position: number = text.search(/\bis\b/);

console.log(position); // 5
