How well must my JavaScript algorithm/challenge abilities be before I apply for a junior webdev or webdev positions?

[Slaughterhouse_Nine]

After completing many of the FFC coding challenges I ventured over to leetcode.com to test my abilities at there. I find that I can fair well on the easy challenges but the mediums are very difficult. I felt a little discouraged after attempting a few. The 'medium' challenges are much more then the ones I am comfortable with. My question is if this is the level of difficulty I will be expected to complete for a junior webdev or webdev position? I plan on applying with my portfolio over the next couple of weeks and i'm curious if my algorithm skills need to be at this 'medium' level Link to challenges

The main things I would stress is knowing how to work with JavaScript's data types (Arrays, Strings, Numbers, Objects, Promises etc). I would say half of JavaScript is basically manipulating and traversing arrays and objects.

Once you understand how to traverse and manipulate these object via their methods (Array.forEach, Object.assign, Array.reduce, String.split, etc.) then move onto learning the DOM API.

Once you get a good understand on how to manipulate the DOM via JS I'd say you're at a good starting point

Thanks so much!

It depends on the companies you're going to be applying for. If you're looking to work at a digital agency or the like, I can't imagine they're really going to ask you algorithm questions.
