    Installation

    Install package :

    And have fun !

    Usage

    Type checkers

    isArray([]); // → true
    isBlob(new Blob()); // → true
    isBoolean(false); // → true
    isDate(new Date()); // → true
    isError(new Error()); // → true
    isFile(new File()); // → true
    isFunction(() => {}); // → true
    isMap(new Map()); // → true
    isNull(null); // → true
    isNumber(1); // → true
    isObject({}); // → true
    isRegExp(/^foo(bar)?$/); // → true
    isSet(new Set()); // → true
    isString('foo'); // → true
    isSymbol(Symbol()); // → true
    isUndefined(undefined); // → true
    isWeakMap(new WeakMap()); // → true
    isWeakSet(new WeakSet()); // → true
    isPrimitive('foo'); // → true

    Arrays

    isArrayOfBooleans([true, false]); // → true
    isArrayOfDates([new Date(), new Date()]); // → true
    isArrayOfNumbers([1, 2, 3]); // → true
    isArrayOfObjects([{}, {}]); // → true
    isArrayOfPrimitives(['foo', 1]); // → true
    isArrayOfStrings(['bar', '1']); // → true

    Objects

    hasKey({ foo: 'bar' }, 'foo'); // → true
    hasValue({ foo: 'bar' }, 'bar'); // → true

    Numbers

    isFiniteNumber(2); // → true
    isGreaterThan(700, 500); // → true
    isInteger(21); // → true
    isLessThan(300, 500); // → true
    isBetween(2, 1, 3); // → true

    Others

    isEmptyArray([]); // → true
    isEmptyObject({}); // → true
    isEmptyString(' '); // → true
    isEqual('foo', 'foo'); // → true
    isHexadecimal('F1F1F1'); // → true
    isIP('210.23.51.230'); // → true
    isJSON('{ "foo": "bar" }'); // → true

    More examples

    isEqual - works with array, boolean, null, number and string

    // Array
    isEqual([1, 'foo', 'bar'], [1, 'foo', 'bar']); // → true
    isEqual([1, 'foo', 'bar'], ['foo', 1, 'bar']); // → false
    
    // Boolean
    isEqual(false, false); // → true
    isEqual(true, false); // → false
    
    // Null
    isEqual(null, null); // → true
    isEqual(null, 'foo'); // → false
    
    // Number
    isEqual(1, 1); // → true
    isEqual(1, '1'); // → false
    
    // String
    isEqual('foo', 'foo'); // → true
    isEqual('foo', 'bar'); // → false

    isIP - only works with string

    isIP('127.0.0.0'); // → true
    isIP('0.0.0.0'); // → true
    isIP('255.255.255.255'); // → true
    
    isIP('192.168'); // → false
    isIP(19216801); // → false
    isIP('127.000.000.000'); // → false

    isJSON - only works with string or null

    isJSON('{}'); // → true
    isJSON('null'); // → true
    isJSON('{ "foo": "bar" }'); // → true
    isJSON(null); // → true
    
    isJSON({}); // → false
    isJSON({ foo: 'bar' }); // → false
    isJSON(''); // → false
