find the kth index of a character in a string in javascript

To find the kth index of a character in a string in Javascript, we can use the charAt() method. The charAt() method returns the character at a given index in a string.

To get the kth index of a character in a string, we can use the charAt() method along with the substring method.

Here's an example:

index.tsx
let str = "Hello World";
let kthIndex = 4; // kth index of the character we want to retrieve

let character = str.charAt(kthIndex); // get the character at the kth index

console.log(character); // output: o

209 chars
8 lines

In the above example, we have a string "Hello World" and we want to retrieve the character at the 4th index (which is 'o'). We first set the kthIndex variable to 4, and then use the charAt() method to get the character at that index.

Note that string indices start from 0, so the first character in a string is at index 0, the second character is at index 1, and so on.
