Lodash _.isObjectLike

Overview

The lodash _.isObjectLike method is a utility function that checks whether a given value is an object-like value. This method determines whether the value is not null and is of type "object". It is often used to determine whether a given value can be treated as an object in various operations, such as iteration or property access.

The _.isObjectLike method is a part of the larger array of utility functions provided by the popular JavaScript library called Lodash. This library provides a set of methods that extend the functionality of JavaScript's built-in objects and functions, and makes it easier to write more robust and maintainable JavaScript code.

The _.isObjectLike method takes a single parameter, which is the value to be checked:

_.isObjectLike(value)

Here, value can be any JavaScript value, such as a primitive value, an object, or a function. The method returns true if value is an object-like value, and false otherwise.

An object-like value is any value that is not null and has a typeof value of "object". This includes plain object literals, objects created using new Object(), objects created using a constructor function, arrays, and other object-like values such as DOM elements.

Here are some examples of using the _.isObjectLike method:

_.isObjectLike({}); // true
_.isObjectLike([]); // true
_.isObjectLike(new Object()); // true
_.isObjectLike(document.createElement('div')); // true

_.isObjectLike(null); // false
_.isObjectLike(undefined); // false
_.isObjectLike('hello world'); // false
_.isObjectLike(() => {}); // false
_.isObjectLike(123); // false

Overall, the _.isObjectLike method is a useful utility function that can help determine whether a value can be treated as an object in various JavaScript operations. It is particularly useful for checking the type of values that can be passed as parameters to functions that expect objects.
