I want to change the text in a .txt with just a few lines of code but have not been able to find anything that, to a 100%, fulfills my purpose.

This is how the situation looks like:

This is how I imagine it to look like:

File myFile = "myTextDoc.txt";
myFile.text = "2";

I know this ain't the right way but I hope it can better picture how I want it to work.

Thanks

Edit: I know how to get the text from the -txt-file to a string and change it but I don't know and send it back to the .txt-file.

Where is this code to be run? – evolutionxbox Nov 23 '21 at 17:26

Read the file into a string. Parse the string with `parseInt()`. Add 1 to the result. Write the result back to the file. – Barmar Nov 23 '21 at 17:27

If you don't know how to read and write files from JavaScript, there are tutorials that will help you. – Barmar Nov 23 '21 at 17:28
He meant does it run on the client or server? – Barmar Nov 23 '21 at 17:30
@evolutionxbox it will be run on a server – Vincent Lindell Nov 23 '21 at 17:47
@Barmar I've searched a lot and I just find overcomplicated scripts that don't work for me anyways. Therefore I wonder if there is any simple way to do it. – Vincent Lindell Nov 23 '21 at 17:48
