Revision 3 of this benchmark created on

Setup

const arrayWithModuleTypes = new Array(100).fill(true).map((_, index) => `module${index}`)

const objectWithModuleTypes = new Array(100).fill(true).reduce((acc, curr, index) => { return {...acc, [`module${index}`]:`module${index}`}}, {})

const setWithModuleTypes = new Set(arrayWithModuleTypes)
