Tricky JavaScript Interview Questions | #0076 #javascript

Welcome to Coding Frontier,
In this video, we’ll explore how JavaScript allows you to access methods directly on a number using bracket notation.

Explanation:

In JavaScript, numbers have methods like toString. By using bracket notation (100['toString']), we can access these methods. The length property of a method indicates how many arguments the method expects, and for toString, it’s 1. Adding 1 gives the final result of 2.

Key Takeaway: You can use bracket notation to access methods on numbers, and the length property reveals the number of parameters the method accepts.
