isMangled
A simple one-liner to help determine whether the code you're executing had been minified or not.
Usage example
let isProduction = false if isProduction = true
Note that this is not a completely foolproof way of determining whether the code had been concatenated or otherwise altered. Some algorythms do not minify code this way, which means you should always test before relying on this function.
Installing
Install with npm i -S is-mangled
or if you're even cooler, use yarn: yarn add is-mangled
.
