@sa0001/type-of

NPM

A library which returns an accurate type for any possible value.

The following standard types are known to work correctly:

• arguments
• array
• boolean
• date
• error
• float32array
• float64array
• function
• int16array
• int32array
• int8array
• map
• null
• number
• object
• promise
• regexp
• set
• string
• symbol
• uint16array
• uint32array
• uint8array
• uint8clampedarray
• undefined
• weakmap

However because Object.prototype.toString.call(val) is used, a type does not have to be in this list for it to return the correct value.

Install

npm install @sa0001/type-of

Usage

const typeOf = require('@sa0001/type-of')

typeOf(arguments) // "arguments"
typeOf(['a',1]) // "array"
typeOf(true) // "boolean"
typeOf(new Date()) // "date"
typeOf(new Error()) // "error"
typeOf(function(){}) // "function"
typeOf(null) // "null"
typeOf(1.23) // "number"
typeOf({a:1}) // "object"
typeOf(new Promise()) // "promise"
typeOf(/\w/) // "regexp"
typeOf(new Set()) // "set"
typeOf('abc') // "string"
typeOf(Symbol('a')) // "symbol"
