Package Exports

babel-helper-evaluate-path

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (babel-helper-evaluate-path) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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 --save-dev
