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

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.
