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

isArrayOfNumbers([1, 2, 3]); // → true
isArrayOfObjects([{}, {}]); // → true
isArrayOfPrimitives(['foo', 1]); // → true
isArrayOfStrings(['bar', '1']); // → true
Objects

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
