Proposal: [API Reference] Write Compressed Code To File

[akhabibullina]

Hello,

When use the library from JavaScript, one can specify the file name to read code from. For example, for "minify" function:

var result = UglifyJS.minify("/path/to/file.js");

Thus, usually a dev doesn't care about manual reading code from the file.
On the contrary, the library doesn't support saving compressed code string to a file. Hence, if the developer needs minified code to be writen in the output file then he/she will also add something like:

// Output to a file
var fs = require('fs');
fs.writeFile(""/path/to/output/file.js", result.code, function(err) {
if(err) {
console.log(err);
} else {
console.log("The file was saved!");
}
});

I propose to add an appropriate option to output object which a programmer may pass as an argument to emit an output file with compressed result code.

Thanks,
Anna.
