Check if a value is an object
Keep in mind that array, function, regexp, etc, are objects in JavaScript.
See is-plain-obj if you want to check for plain objects.
$ npm install is-obj
import isObject from 'is-obj';
isObject({foo: 'bar'});
//=> true
isObject([1, 2, 3]);
//=> true
isObject('foo');
//=> false
is-plain-object is a package that checks if an object is a plain object, that is, an object created by the Object constructor or one with a null prototype. It is similar to is-obj but also checks if the object is created by the Object constructor, which is-obj does not do.
isobject is another npm package that checks if a value is an object and not an array or null. It is similar to is-obj but also returns true for functions, which is-obj does not.
lodash.isplainobject is a method from the popular Lodash library that checks if a value is a plain object. It is more comprehensive than is-obj as it includes additional checks to determine if the object is plain.
