prototypeof

👌 Simply get the type of an object.

prototypeof is a simple function to get the type of an object by using Object.prototype.toString on any given object. Usually, this is always the best way to guess the type of an object since typeof may return things not expected (Array and Null are considered object).

Furthermore, even when using Object.prototype.toString, there’s no easy way to make custom types names. That’s why I created prototypeof.

The name may look misleading (we’re not actually getting the prototype), but is etymologically correct. Which corresponds to πρωτο- (prōto-) (most recent ancestor) and type.

Getting Started

const prototypeof = require('prototypeof');

class Type {
    constructor() {
    }
}

var type = new Type();
console.log(prototypeof(type)); // "Object"
console.log(prototypeof(Type, 'Type')); // "Type"
console.log(prototypeof(type)); // "Type"

JavaScript API

prototypeof ( object[, type])

Get the type of an object and optionally set its type. If the object has a prototype, set the prototypal type. Finally return the type name.

• object: Any objects or primitives.
• type: Optional. If truthy, set the type name.
• Return: A type name as a String.
