The Quintessential Guide For Cracking JavaScript Interviews For Developers World-wide

JavaScript will be the hot thing and isn’t going anywhere for the next 5 years!

For several years now, we’ve seen a huge demand for JavaScript developers world-wide. If you want to get a programming job quickly, this is the language to learn. Not only that, there’s always something new coming up every now and then, so you need to be updated about the latest changes and industry trends.

Others say that cracking JavaScript interviews is complicated. I say it is NOT! If you have the right resources and up-to date information – learning JavaScript is easy and fun. I have built this course for individuals who are facing difficulties in cracking JavaScript interviews – keeping one thing in mind – answering each and every question in the simplest of ways!

Why JavaScript only?

I am sure you want to learn Angular, Node.js, React, Vue JS, Typescript, Svelte, or any other framework to be the best in the business, but at the end of the day, JavaScript fundamentals are the key because understanding and learning JavaScript is an investment that will certainly pay off for you in the future.

With my 23+ years of experience in the programming industry – I’ve put all my JavaScript knowledge and teaching experience in building this comprehensive course. I’ve made sure there’s everything required for freshers as well as experienced individuals. With that being said – I am working on a progressive course update plan where I’ll add new lectures from time to time because JavaScript is an ocean and I need to dive deep to bring out the best and the most precious questions/concepts pearls for you!

The course is based on my experience as a teacher with thousands of students across platforms like Udemy as well as my YouTube channel “Nirmal Joshi”. It’s packed with all sorts of real-world interview and assessment questions which are asked in IT development companies – all with the goal of giving you the best possible way of learning JavaScript in the simplest ways.
