    Type

    This Project adds better type checking from basic JS types.

    Installation

    npm install --save @philipp122/type
    

    Usage:

    Type supports 14 primitive JS Types: Undefined, Null, Boolean, Number, NaN, Infinity, String, Symbol, Array, Object, WeakSet, Set, WeakMap and Map as well as 2 aliases of Number: Integer and Float.

    Any value can be checked against those types:

    const Type = require('@philipp122/type');
    
    // ALL of the following return true
    console.log(undefined instanceof Type.Undefined);
    console.log(null instanceof Type.Null);
    console.log(true instanceof Type.Boolean);
    console.log(5 instanceof Type.Number);
    console.log(5 instanceof Type.Integer);
    console.log(5.5 instanceof Type.Number);
    console.log(5.5 instanceof Type.Float);
    console.log(Infinity instanceof Type.Infinity);
    console.log(NaN instanceof Type.NaN);
    console.log("Hello World" instanceof Type.String);
    console.log(Symbol("Bye") instanceof Type.Symbol);
    console.log([1, 2, 3] instanceof Type.Array);
    console.log({a: 1, b: 2} instanceof Type.Object);
    console.log(new WeakSet() instanceof Type.WeakSet);
    console.log(new Set() instanceof Type.Set);
    console.log(new WeakMap() instanceof Type.WeakMap);
    console.log(new Map() instanceof Type.Map);

    See index.test.js for more examples.
