LeetCode's 30 Days of JavaScript study plan focuses on teaching JavaScript concepts that are essential for real-world software engineering.
It teaches practical patterns rather than just the language basics.
You need to have a reasonable understanding of JavaScript to grasp the concepts taught in this study plan.
It serves to bridge the gap between computer science theory and software engineering.
The challenges in the study plan help create connections between the worlds of computer science and software engineering.
The challenges in this JavaScript study plan build a complete mental model of modern JavaScript, layer by layer.
The sequence of problems isn't random, but rather is building a mental model of modern JavaScript, layer by layer.
This study plan has several blind spots as it assumes a certain level of prior knowledge, some of the challenges can be overwhelming for beginners, but it is still a valuable resource for understanding modern JavaScript.
Counterintuitively, after completing the challenges you will gain the most valuable skill of recognizing the patterns in other people's code.
The real challenge is recognizing how to apply learned patterns in production code.
