Simple utility library with variable type checking functions.

Documentation

The usage is quite simple and obviously, import the function which you need, call the function and do you stuff

import { isString } from "@maksims/is.js";
// do stuff

But there are two functions that may need some explanation, first function is isObject checks is passed value a any valid javascript object exclude null and Array, for example

import { isObject } from "@maksims/is.js";

isObject({})        // true
isObject({
    PI: 3.14,
    sum: (a, b) => a + b
})                  // true
isObject(new Map()) // true
isObject(20)        // false
isObject([])        // false

Second function isRecord function checks is passed value a plain javascript object, for example

import { isObject } from "@maksims/is.js";

isRecord({})        // true
isRecord({
    PI: 3.14,
    sum: (a, b) => a + b
})                  // true
isRecord(new Map()) // false
isRecord(20)        // false
isRecord([])        // false
