JavaScript Tricky Interview Questions

If you’re preparing for a JavaScript interview, you may encounter some tricky questions that can test your knowledge of the language. Here are a few questions that often come up:

Question 1: What is the difference between == and === in JavaScript?

The == operator checks for equality only after coercing both values to a common type, while the === operator checks for equality without type conversion. For example, 1 == ‘1’ will return true, but 1 === ‘1’ will return false.

Question 2: What is hoisting in JavaScript?

Hoisting is a JavaScript mechanism where variables and function declarations are moved to the top of their containing scope during the compile phase. This means that you can use a variable or function before it’s declared in your code.

Question 3: What are closures in JavaScript?

Closures are functions that have access to variables from their outer scope even after the outer function has finished executing. This can be useful for creating private variables or for maintaining state in a function.

Question 4: What is the event loop in JavaScript?

The event loop is a fundamental concept in JavaScript that allows the runtime to efficiently handle asynchronous events. It processes tasks in a queue, executing them one at a time in a loop, ensuring that the UI remains responsive.

These are just a few examples of tricky JavaScript interview questions that you may encounter. It’s important to have a solid understanding of the language and its quirks in order to ace your interview!
