babel-plugin-fuck-optimization

Use this plugin when you want to see beautiful bailouts in your code.

Transforms this:

function add(a, b) {
  return a + b;
}

into this:

function add(a, b) {
  var __deoptimization = {
    __proto__: "notsofast"
  };
  
  return a + b;
}

It traverses all the BlockStatement and if its parent is FunctionDeclaration, ClassMethod, FunctionExpression or ArrowFunctionExpression (basically all functions in your code) ~~it pushes the new TryStatement with CatchClause within the BlockStatement~~ (optimized in V8 5.3.1) it adds an object literal declaration with modified __proto__ property.
