Welcome all.
I have been doing layout for more than 3 years, freelancing, this is my hobby, which I really like and brings money in addition to my main job.
I don’t have any education in this area, I’m all on my own, but during this time I learned to make layout using HTML, CSS at a good level, JavaScript at the level of connecting ready-made libraries and setting them up for a specific site, I can pull a template on CMS Joomla, Wordpress...
2 months I left my main job (sales manager position) ago and now I want to find a job as an HTML coder in the office, for a constant flow of work, but knowledge of JavaScript is required everywhere.
I understand that it is necessary to know it, I didn’t learn it before because my knowledge was enough for the level of complexity of the projects that I had.
Actually questions:
1. What do web studios mean by the phrase "You must be able to develop websites in JavaScript"? Those. the whole site would need to be done in JavaScript, and even a simple popup menu that could be implemented with CSS would need to be done in JavaScript as well?
2. What changes will knowledge of JavaScript bring to the development process, what will I be able to do?
3. How long will it take (approximately) for me to learn JavaScript at a level so that I can be hired by a web studio as a coder with the knowledge and ability to write at least something simple in JavaScript .
4. How long will it take me (approximately) to learn JavaScript at a level before I get hired by a web studio asFront-end developer with the knowledge and ability to write JavaScript for some long-term project, such as a web service .
PS Thank you in advance for your replies.

The Javascript coder needs at a minimum level solely to enable and configure plugins. Javascript should be handled by a front-end programmer. If his knowledge is required, then this is not a layout designer's vacancy. If this requirement is indicated in the vacancy "HTML maker", then one can doubt the professionalism of the employer.
There is a front-end developer. This is a coder and a programmer, and many more people rolled into one. It should be paid differently.

1. - go to an interview - get the exact answer that a particular office wants from you
2. - all interactive on the client side
3-4. - maybe half a month, maybe half a year - depends on your abilities
IMHO. Without JS, you only need a coder for freelance projects for $5 - fix it there, add it here ... something serious - you need JS right away.

Such advice to you - start learning Javascript today. A coder as a technical profession can collapse very soon and you can accidentally be beaten if you do not take care of this issue in advance.

Why does a coder need to learn JavaScript?

because without JS (namely, JS frameworks), not a single web application is written now. And, most likely, you will have to at least know PHP control structures in order not to faint from templates.

What changes will knowledge of JavaScript bring to the development process, what can I do?

change the DOM at least.

With the help of javascript, you can make dynamic, beautiful, responsive websites. Sending a message, button manipulation, animation, etc. Also suitable for spa. angular js, react.

1. It usually means that you own a framework ( angular , ember ) or a library like react or vue (plus you are familiar with their ecosystem). The framework offers all the necessary "out of the box" tools for building a web application (in this regard, it can be easier for a beginner).
Libraries themselves are a tool for building a user interface, and to build a fully functional application, you will need to turn to third-party tools within the library ecosystem ( but this is not difficult ).
2. Anything. Given that the javascript is wound on the server(isomorphic javascript) thanks to node. You can become a full-stack developer by knowing just one programming language.
3. For a coder, a javascript is needed mainly at the level of manipulation with the house , connecting certain vanilla or not quite libraries .
4. I think at least about half a year to become a junior.
ps knowledge of English at the intermediate level will not hurt.
