What are some common methods for JavaScript objects?
JavaScript objects have several built-in methods like Object.keys()
, Object.values()
, and Object.entries()
. Would you like to know more about any specific method?
Can you explain what Object.keys()
does?
Sure! Object.keys()
returns an array of a given object's own enumerable property names. For example, if you have an object {a: 1, b: 2}
, Object.keys()
will return ['a', 'b']
.
What about Object.values()
?
Object.values()
returns an array of a given object's own enumerable property values. Using the same object {a: 1, b: 2}
, it will return [1, 2]
.
Are there any methods to merge objects?
Yes! You can use Object.assign()
to merge objects. It copies all enumerable own properties from one or more source objects to a target object.
