The is-object npm package is a simple utility that checks if a given value is an object. It is useful for type-checking in JavaScript, ensuring that a value is an object and not another type like a string, number, or array.
Basic Object Check
This feature allows you to check if a given value is an object. The function returns true for plain objects and false for arrays, null, strings, and other non-object types.
const isObject = require('is-object');
console.log(isObject({})); // true
console.log(isObject([])); // false
console.log(isObject(null)); // false
console.log(isObject('string')); // falseThe lodash.isobject package is a part of the Lodash library, which provides utility functions for common programming tasks. lodash.isobject checks if a value is an object, similar to is-object, but it is part of a larger suite of utilities, making it more versatile for various tasks.
The is-plain-object package checks if a value is a plain object, i.e., an object created by the Object constructor or with a null prototype. It is more specific than is-object, which checks for any object type.
The isobject package is another utility for checking if a value is an object. It is similar to is-object but includes additional checks to ensure the value is not an array or null.
Checks whether a value is an object
Because typeof null is a troll.
var isObject = require('is-object');
var assert = require('assert');
assert.equal(isObject(null), false);
assert.equal(isObject({}), true);
npm install is-object
