join an array of characters into a string in javascript

To join an array of characters into a string in JavaScript, we can use the join() method of the array. The join() method joins all elements of an array into a string.

Here is an example code snippet that demonstrates how to use the join() method:

index.tsx
let charArray = ['h', 'e', 'l', 'l', 'o'];
let str = charArray.join('');
console.log(str); // will output: hello
113 chars
4 lines

In the above example, we first defined an array of characters charArray. Then, we used the join() method to join all characters in the array into a single string. We passed an empty string '' as a separator to the join() method, which means that no separator will be used between the characters.

Finally, we stored the resulting string in the variable str and printed it to the console using the console.log() method.

Note that the join() method does not modify the original array, but returns a new string that contains all elements of the array joined together.
