TypeScript - find character index in string

In this article, we would like to show you how to find a character in a string in TypeScript.

Quick solution:

xxxxxxxxxx

'ABC'.indexOf('B')  // 1

To find the character in a string we need to use indexOf() method.

xxxxxxxxxx

const result: number = 'dirask is awesome!'.indexOf('d');

​

console.log(result); // 0

Output:

xxxxxxxxxx

0

xxxxxxxxxx

const myString: string = 'dirask is awesome!';

​

console.log(myString.indexOf('i')); // 1

Output:

xxxxxxxxxx

1

Note:

If there is more than one occurrence of the character, the infexOf() method returns the position of the first one, starting from the left.
