You also need to understand the distinction between a function and a method. Everything is JS is an Object, and it is vital that you understand at a deep level what that means, including prototypes.įunctions, and how they work. Primitive data types (string, number, boolean, etc), and how to operate on/utilize them, including type coercion.īasic data structures (arrays and objects), and how to work with them. You'll know exactly where to turn to find answers to problems or questions that you're running into.įollowing the advice here won't make you a master of JavaScript, but you'll be effective at the day-to-day that you'll need to get started on the job.

There may be gaps in your knowledge, but those will be limited to secondary concepts or syntax/other details that you'll be able to find the answer to relatively quickly and easily. You'll understand the broad strokes of the technology in question, and know the most fundamental concepts that come up every day. I will also not be touching on some important related tools such as npm or bundlers, but I will be discussing those in a future post.īefore starting, let me clarify precisely what I mean when I say 'job-ready:

I will also mention that I'll only be discussing vanilla JS in this post, and Node, React, etc are out of the scope of this discussion.

I consider JavaScript harder to learn than CSS (especially if it's your first traditional programming language), but easier to master once you do have those fundamentals down. $('form#register').find('input').Today, we're going to cover JavaScript, the last of the three foundational technologies used in web development. What would be the easiest way to check if an input is required? I have been trying stuff along these lines but always comes up with all required (only 4/6 are).
