babel-helper-evaluate-path

A wrapper for babel's path.evaluate

Fixes / Features:

• Detect usages before initialization / declaration

function foo() {
  console.log(b); // ReferenceError
  let b = 1;
}

function bar() {
  console.log(a); // a is void 0
  var a = 5;
  console.log(a); // 5
}

• Detect usages in scopes outside of initialization for vars (hoisted)

function foo() {
  if (a) var x = 5;
  console.log(x); // cannot determine
}

Installation

npm install babel-helper-evaluate-path
