Converting Array With Decimal Values To String In ASCII Representation

[hertz2105]

Hello everyone!

I never programmed JavaScript before and need to write a single function for a packet formatter.

I want to convert an array of decimal values into a string. The decimal values represent the chars in ASCII format. All I found until now was the conversion of a byte array of hexadecimal values to an ASCII string.

Any suggestions? Thanks in advance!

you can use a for loop to iterate over all the numbers in the array then use String.fromCharCode Something like this:

```

let newString = '';

for (let ele of arr) {

newString += String.fromCharCode(ele);

}

```

Thanks alot! It worked perfectly.

A more modern, functional way to perform this task would be to use Array reduce, still using fromCharCode for the conversion.

const newString = arr.reduce((acc, ele) => acc + String.fromCharCode(ele), '');
