A large majority of modern web applications are built with Javascript… Both frontend and backend. You do still have a large majority of websites using plain HTML or PHP, with some features requiring JS to function (modals, realtime stats, data input, etc).
You also have alternative languages like Java or C# (and more), but also may use bits of JS on the frontend to drive functionality.
You can bet that the majority of websites you visit nowadays will use some form of JS, unless it’s a static webpage to display basic information.
If it’s just fries, then nothing other than salt.
Otherwise, cheese curds and gravy.
A lot of it has been family and college. The college I attended has a research group that allows students to do internships.
The college also runs job fairs every one in a while. Those kinds of things I huge.
Conventions of any kind as well, where you can speak to people in booths, or even any of the other attendees.
My first ever job was running a wood chipper under my uncles tree business. Did that almost every weekend for a number of years. Even sometimes in the winter. I wasn’t even a teenager when I first started this job.
Second job was working in a warehouse at a company my mom worked at. They really needed weekend help.
My third job was doing landscaping over the summer at a smallish company where my brother in law worked at. The owner loved to hire students for cheap.
Fourth was a few of software development internships ran by a research group at my college. I had a friend who was part of the group and vouched for me.
My current job is my first true career job as a software engineer. The project manager from one of the internships I had actually got a job as CTO at this company. Offered me a junior position there out of college. Been there almost 6 years.
I have applied to places where I certainly would have needed interviews, but I was never offered an opportunity.
To make this even more awesome is that I’ve interviewed candidates myself at my current job for junior positions.
