Summary if you like
The Most Failed JavaScript Interview Questions&quot; by IntSpirit, discusses some of the most commonly failed JavaScript interview questions. The author argues that these questions are important for aspiring web developers to understand, as they reflect core concepts of the language.
The first question discussed is about the difference between null and undefined. The author explains that null is an intentional absence of value, while undefined means that a value is not assigned. They suggest that interviewees should have a clear understanding of the distinction between these two values.
The second question concerns JavaScript’s hoisting mechanism, which allows developers to use functions and variables before they are declared. The author emphasizes the importance of understanding the scope of variables and how hoisting can impact their behaviour.
The third question asks about the difference between synchronous and asynchronous code execution. The author explains that synchronous code executes in a sequential manner, while asynchronous code allows for non-blocking execution. They suggest that candidates should have a good understanding of how to use callbacks, promises, and async/await to manage asynchronous code.
The fourth question discussed is about the “this” keyword in JavaScript, which can be confusing due to its dynamic binding. The author recommends that interviewees should have a clear understanding of how “this” works in different contexts, such as with arrow functions or within object methods.
Finally, the article covers some additional tips for preparing for JavaScript interviews, such as practicing coding challenges and understanding common data structures and algorithms. The author emphasizes that while these questions may seem daunting, a strong understanding of these concepts will help candidates succeed in their interviews and become better developers overall.

Can u share the most asked questions in javascript interview I’m preparing for interview now…

If you have a few companies you have worked at and many years of experience. JavaScript interview questions are a waste of time. These tests don’t determine if your a good programmer or not

Super helpful for my interview on Monday 👍

I just left a job where I coded in Node/JavaScript for a bit over 4 years. I wasn’t asked any of these questions then, and none of these questions in the dozen or so interviews I had before finding a new job. Good stuff to know, no doubt, but hard to believe that these questions are commonly asked during interviews. Maybe at a FAANG. Still, would take this articles advice with a grain of salt
