Useful Object Methods in JavaScript

When working with JavaScript, understanding how to manipulate objects is essential. Here are some useful object methods in JavaScript that you will need:

Object.keys()

The Object.keys() method returns an array of a given object’s own enumerable property names. This method can be helpful when you need to loop over the keys of an object.

Object.values()

The Object.values() method returns an array of a given object’s own enumerable property values. This can be useful when you need to access the values of an object.

Object.entries()

The Object.entries() method returns an array of a given object’s own enumerable property [key, value] pairs. This method can be handy when you need to work with both keys and values of an object.

Object.assign()

The Object.assign() method is used to copy the values of all enumerable own properties from one or more source objects to a target object. This can be useful when you need to merge the properties of multiple objects.

Object.freeze()

The Object.freeze() method freezes an object, preventing new properties from being added to it and existing properties from being removed or changed. This can be helpful when you want to make an object immutable.

These are just a few of the many useful object methods available in JavaScript. By mastering these methods, you can become more proficient at working with objects in your JavaScript applications.
