# Why Learn JS?
JavaScript is the only language that lets you do every aspect of technology.
This is misleading at best.
I agree, I haven't had time to revisit it to improve the wording, will do it tonight. This is really what I meant:
Our decision behind JavaScript:
We want our students to understand technology at a conceptual level first, end to end:
1. Client side - Mobile, web, terminal 2. Server side - Database interactions, system design and optimization 3. Batch - ML models and scripting
AFAIK, JavaScript is the only language that is able to cover everything end to end (front end to backend to scripting to even ML) so I'm able to come up with appropriate exercises for each of the moving parts.
Afterwards, they should pickup domain specific language that optimizes for each task.
I think it may be too overwhelming for students to learn different languages and learn the high level concepts at the same time.
Unfortunately, there may be more instances of word choices. Each lesson is about 4-5k words (totaling 30k) and I simply don't have enough time to think critically on every word so feedback like these helps. Feel free to bring these up in the chatroom and help us improve our wording!
I think you are right and I'm annoyed that you are. Because I think JavaScript is a really hard language to master. Ubiquitous yes, versatile yes but so full of cruft and bad design decisions that it really can put many people off programming.
I think you may find that some of those "bad design decisions" are actually not so bad, or at least manageable, once you will have read through the book.
