What are the keys of a JavaScript object?
In JavaScript, the keys of an object are the property names that you can use to access the values. For example, in the object { name: 'Alice', age: 25 }
, the keys are 'name' and 'age'.
How can I get all the keys from an object?
You can use the Object.keys()
method to retrieve an array of keys from an object. For example, Object.keys(myObject)
will return an array of keys.
Can you show me an example?
Sure! Here's an example:
const person = { name: 'Alice', age: 25 };
const keys = Object.keys(person);
console.log(keys); // Output: ['name', 'age']
