Strid

Get a unique string identifier for any input value.

Details

• All values that are the same according to Object.is will have the same string identifier.
• All values that are different according to Object.is will have different string identifiers.
• If your engine hasn't implemented this proposal then input symbols will be kept in memory indefinitely.

Install

npm install strid

Usage

// Let's get a unique string identifier for some values
