realtypeof
This is a very simple and light package to get the real type of values.
Installation
$ npm install realtypeofUsage
const realTypeOf = require('realtypeof');
realTypeOf(45); // 'number'
realTypeOf('hello'); // 'string'
realTypeOf(true); // 'boolean'
realTypeOf(null); // 'null'
realTypeOf(undefined); // 'undefined'
realTypeOf(Symbol()); // 'symbol'
realTypeOf([]); // 'array'
realTypeOf(() => {}); // 'function'
realTypeOf({}); // 'object'
realTypeOf(new Map()); // 'map'
realTypeOf(new Set()); // 'set'
realTypeOf(new WeakMap()); // 'weakmap'
realTypeOf(new WeakSet()); // 'weakset'The type of returned value is always string
You can also check the type of value whether it is a particular type:
realTypeOf.isNumber(45); // true
realTypeOf.isString('hello'); // true
realTypeOf.isBoolean(true); // true
realTypeOf.isNull(null); // true
realTypeOf.isUndefined(undefined); // true
realTypeOf.isSymbol(Symbol()); // true
realTypeOf.isArray([]); // true
realTypeOf.isFunction(() => {}); // true
realTypeOf.isObject({}); // true
realTypeOf.isMap(new Map()); // true
realTypeOf.isSet(new Set()); // true
realTypeOf.isWeakMap(new WeakMap()); // true
realTypeOf.isWeakSet(new WeakSet()); // trueThe type of returned value of these methods is always boolean
