Babel Plugin Transform Equal Chain

A basic transformer which simplifies multiple equal statements.

It takes something like this

typeof something === "string" || typeof something === "number" || typeof something === null

Which can be written like this, but outputs to the example above

typeof something === ("string" || "number" || null)

It workes with both loose and strict equality

// strict
typeof something === (null || undefined || true)

// loose
typeof anotherThing == (null || undefined || true) 

Installation

npm i babel-plugin-transform-equal-chain
