To get the length of an object in JavaScript:

  1. Pass the object to the Object.keys() method as a parameter.
  2. The Object.keys() method returns an array of a given object's own enumerable property names.
  3. Use the length property 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.
