I wish people wouldn't do this. LeetCode is not programming. It's a very specific sort of algorithm-based problem solving that almost never comes up in real day-to-day programming. It's really good for one thing only, and that is passing the interviews for the specific type of software companies that use these sort of problems in interviews. Note that almost all companies do not use these problems, although unfortunately those that do are among the biggest players (Google, Meta, etc). Learning how to solve LeetCode won't help you be a better programmer. Learn to program first, then after a few years if you think you want to try for one of these companies by all means learn how to do LeetCode. More on reddit.com

Honestly I think the best way js to learn as you go. I find I remember stuff more once I use it in a problem. Like if you do a question that requires a heap simply google heap in python and do the problem. More on reddit.com

Leetcode is not the only way. I never use it, and I had never heard about it when I got my first dev job. I find it much more satisfying and challenging to create my own projects, and learn about best practices etc. while working on them. Solving random, generic coding challenges online can be fine if you learn better this way. You just don't learn anything about the bigger picture. If you want coding problems, but with more structure, the book "Elements of Programming Interviews in Python" is a much better source imo. More on reddit.com
