How to get the length of an object in JavaScript
To get the length of an object in JavaScript:
- Pass the object to the
Object.keys()method as a parameter. - The
Object.keys()method returns an array of a given object's own enumerable property names. - Use the
lengthproperty to get the number of elements in that array.
Here is an example:
const user = {
name: 'John Doe',
age: 23,
country: 'United States'
}
const length = Object.keys(user).length
console.log('Object length is ${length}')
// Object length is 3
In the above code, we used the Object.keys() method to get an array of the object's keys. The length property of the keys array returns the count of key-value pairs in the object.
