usage
We can use this with,
esshorten.mangle(AST);
And we can pass options to mangler,
esshorten.mangle(AST, {
// If false, AST is copied deeply (default: true)
destructive: false,
// If false, avoid [JSC bug](https://github.com/mozilla/sweet.js/issues/138) (default: false)
distinguishFunctionExpressionScope: false,
ecmaVersion: 6 // 5 , 6,
sourceType: 'script' // script or module, nodejs using module type
});
When destructive option is set to false, esshorten copies AST and modifies it.
