    babel-plugin-check-es2015-constants

    Validate ES2015 constants (prevents reassignment of const variables).

    Example

    In

    const a = 1;
    = 2;

    Out

    repl: "a" is read-only
      1 | const a = 1;
    > 2 | a = 2;
        | ^

    Try in REPL

    Installation

    npm install --save-dev babel-plugin-check-es2015-constants

    Usage

    Via .babelrc (Recommended)

    .babelrc

    {
      "plugins": ["check-es2015-constants"]
    }

    Via CLI

    babel --plugins check-es2015-constants script.js

    Via Node API

    require("babel-core").transform("code", {
      plugins: ["check-es2015-constants"]

    This check will only validate consts. If you need it to compile down to var then you must also install and enable transform-es2015-block-scoping.
