Nail the Javascript technical interview

Are you prepared for your software developer technical assessment? In this video I’m going to do a mock frontend online assessment / technical interview for junior and intermediate software developers. These are the most common questions I’ve encountered in interviews for frontend positions. We’re going to use React and go over the most common JavaScript array methods.

Me in the interview: "Before you ask me any questions, I just want to say that if you waste my time with keyword 'var' or the scope of 'this', then I'm leaving."

Your tone of voice is so comfortable to listen to and your videos are really helpful. Thank you so much for sharing these videos

how i only stumbled into this channel now, I'm watching all the videos regarding interviews and javascript and you do such a good job of actually explaining from experience, if i manage to land a job this channel will definitely be part of the reason why!

Great video! I have a technical interview coming up and this is helping me prepare and calm my nerves a little!

Watching right before bed, relaxing video & simple overview of Array.map Array.reduce Array.sort & Array.filter! The trickiest stuff for me is always dealing with object structure (I completely forgot about hasOwnProperty), which gets even hairier when you're working with immutable objects.

Awesome video! Thank you for the rundown.

Absolutely clapped when you used an object map for the second part, it would have been great to hear the "CS" explanation as to why that's a good data pattern "O(1) lookup, etc" for the junior engineers.

Question about using a const sortedArray with a for in loop versus Is it perf? Cleanliness? Ease of reading?

I like the problems in this video, a nice challenge and really makes you think. Nice work.

Really great video. I'm gonna have an interview this week and I'm super nervous. When I follow I understand everything, when I have to do it alone without my notes I panic. 🤞

I love how at the beginning you said that they would likely give this type of assessment over a leetcode one. I wish they'd do that for all levels. Wishful thinking, am I right?

I'm a senior Frontend dev. I'm starting to wonder if leetcode is the only way up nowadays. Some companies have done straightforward JavaScript tests which is fine.

[jonathanjohnson]

Thanks so much. I'm getting nervous just thinking about this process.

How come you didn’t set the input element's value attribute to the state variable, in the last question?

Also keep up these type of videos. Extremely helpful. Liked

Can we use notes during a junior frontend interview? What if I understand all of this but I need to look at my documentation, code snippets, or written explanation to help explain what I am doing.

how to use reduce?, but with typescript.

I will never interview for a javascript job lol
