Type Checks

This feature allows you to check the type of a given value. The `isString` function checks if the value is a string, and the `isNumber` function checks if the value is a number.

const { isString, isNumber } = require('@thi.ng/checks');

console.log(isString('hello')); // true
console.log(isNumber(123)); // true
console.log(isNumber('123')); // false

Array Checks

This feature provides functions to check if a value is an array and if an array is empty. The `isArray` function checks if the value is an array, and the `isEmptyArray` function checks if the array is empty.

const { isArray, isEmptyArray } = require('@thi.ng/checks');

console.log(isArray([1, 2, 3])); // true
console.log(isEmptyArray([])); // true
console.log(isEmptyArray([1])); // false

Object Checks

This feature includes functions to check if a value is an object and if an object is empty. The `isObject` function checks if the value is an object, and the `isEmptyObject` function checks if the object is empty.

const { isObject, isEmptyObject } = require('@thi.ng/checks');

console.log(isObject({ a: 1 })); // true
console.log(isEmptyObject({})); // true
console.log(isEmptyObject({ a: 1 })); // false

Function Checks

This feature provides a function to check if a value is a function. The `isFunction` function checks if the value is a function.

const { isFunction } = require('@thi.ng/checks');

console.log(isFunction(function() {})); // true
console.log(isFunction(() => {})); // true
console.log(isFunction(123)); // false

console.log(isString('hello')); // true
console.log(isEmptyString('')); // true
