Answer 1

I just made a script that runs in the Node and removes "use strict"; in the selected file.

file: script.js:

let fs = require('fs');
let file = 'custom/path/index.js';
let data = fs.readFileSync(file, 'utf8');
let regex = new RegExp('"use\\s+strict";');
if (data.match(regex)){
    let data2 = data.replace(regex, '');
    fs.writeFileSync(file, data2);
    console.log('use strict mode removed ...');
}
else {
    console.log('use strict mode is missing .');
}

node ./script.js
