find the kth character in a string in javascript

To find the kth character in a string in JavaScript, you can use the charAt() method of the string. The charAt() method takes an index as a parameter and returns the character at that position in the string.

Here's an example of how to find the kth character in a string:

index.tsx
const str = "Hello, World!";
const k = 6;
const kthChar = str.charAt(k-1);
console.log(kthChar); // Output: ,
110 chars
5 lines

In the above code, we first declare a string "Hello, World!" and a variable k as 6, which represents the index of the character we want to find. We subtract 1 from k, as the index of the first character in a string is 0 and so on. Then, we use the charAt() method to get the character at the kth position in the string, and store it in the variable kthChar. Finally, we log the value of kthChar to the console, which gives us the kth character in the string.
