esprima Unexpected token =>

[Gaeta]

Code:
`var codeProtect = require('code-protect');
var option = {
sourceDir: './Bot',
destinationDir: './BotCode',
uglify: true,
debug: true
};

codeProtect(option, function (err, data) {
if (err) {
throw err;
} else {
console.log(data);
}
});`

error: \node_modules\esprima\esprima.js:5702 throw e; ^ Error: Line 121: Unexpected token =>

I know this is an old project just wondering on if this can be fixed?
