I'm writing a code in JavaScript the opens a file then read it:

var txtFile = "/dataset/happy.txt";
var fileH = new File(txtFile);
var fileS = new File("/dataset/sad.txt");
var fileA = new File("/dataset/angry.txt");
var fileSC = new File("/dataset/scared.txt");
var fileSU = new File("/dataset/suprised.txt");

fileH.open("r"); // open file with read access

But I get (ReferenceError: File is not defined) error What's the problem?

Thank you :)

Which browser are you working on? Read the supported browser list: https://developer.mozilla.org/en-US/docs/Web/API/File – Raptor Feb 01 '18 at 09:16
What ever browser/environment you're working with doesn't support the Feile API – Andreas Feb 01 '18 at 09:17
@Raptor I'm working on Cloud9 and I tried both chrom and edge – user8423460 Feb 01 '18 at 09:20
Where did you read about a `File` type that would work this way? – Ry- Feb 01 '18 at 09:24
@Ryan This is what I found when I searched Google. Also: https://gist.github.com/Arahnoid/9925725 – user8423460 Feb 01 '18 at 09:30

That appears to be for Photoshop automation. Not going to work in Node.js/browser/anything else. – Ry- Feb 01 '18 at 09:33
@Ryan So What's the solution? – user8423460 Feb 01 '18 at 09:36
Look up documentation appropriate to the platform you want to use. Are you trying to write a Node.js project? – Ry- Feb 01 '18 at 09:37
@Ryan Yes exactly – user8423460 Feb 01 '18 at 09:38
https://nodejs.org/api/fs.html#fs_fs_readfile_path_options_callback but you should probably start with a Node.js tutorial, or by learning JavaScript without the Node parts first. – Ry- Feb 01 '18 at 09:40
