How to save the output of a particular variable in a text file (javascript)?

Question

How can we save the output of a particular variable in a text file?

I want to call a variable inside a function and save it in a txt file

I also want each file to have a specific name that I want

like sum.txt sum1.txt

variable names with a number

I want it to be in javascript not PHP

Sorry to say but if you mean writing the file to users disk, then you simply cannot do that because writing to a file directly using js would have had a great sequrity risk.

All you can do is to ask browser to download a file with variable content with custom name but that will always be on /sdcard/downloads/yourfile.txt on phone and C:\\downloads\yourfile.txt on windows(not sure about windows though, someone correct me if im wrong).

If youre talking doing it server side using node.js:

Then you can do like

const fs = require('fs');
fs.writeFile("/tmp/test", your_var, function(err) {
if(err) {
return console.log(err);
} else {
console.log("The file was saved!");
}
});

Hope this helps!!!
