Love your channel Connor, was wondering if you and Clement were gonna do more mock interviews soon? Especially for most entry level jobs like the CSS one you guys had , not crazy FAANG interviews haha.

Do you use typescript or do you prefer JS

[@ConnerArdman]

It just depends on the situation. For a quick project/script, I usually won’t bother with TypeScript. But for a larger project, I’d pretty much always use it.

[@AbusiveInfected]

First trick, don’t use JS and enjoy your life. Thank you for coming to my Ted Talk.

[@elg281]

Cool as soon as i learn JS.

[@ConnerArdman]

The best time to start is now 🤪

[@FFFL1000]

first!

[@betomoedano]

Great video! I would like to see a desktop tour 👍

[@ConnerArdman]

Thanks! A lot of people have asked for that, so I’ll probably make a short about it eventually 👍
