Just google stuff when you need them. It’s not like “classic” learning where you need a stack of reference books. Everything is online and is constantly changing. I find mdn to be a good place for HTML, CSS, and JavaScript reference. The docs are always a good place for any library. Stack Overflow is good for general questions. But google will pop those up with a well worded question.
Also, would I be able to put these certificates in my resume.
As mentioned, you can put them on your resume (I did) but no employer is going to say, “Wow! This guy has some certificates from an online, free self-paced, self-evaluated bootcamp!” Sure, put them on. But the real value is what you learn, what you build, and what you’re staged to build after you leave the boot camp.
Also i wanted to know if I can become a front-end developer if I don’t go to a university.
Sure. It’s a little easier if you have a CS degree. Baring that, any degree helps. But yeah, people do get hired with no degree. If you can build a killer portfolio and convince them in the interview that you are professional, self-motivated, and detail oriented … then yeah, it can be done.
Me, I studied a little programming decades ago and had an non-tech advanced degree. I got a job. I’ve worked with people with CS degrees, with other degrees, only had boot camp, and were only self-taught. Some companies will only hire CS degrees. But some like a mix, some even prefer non-uni people.
I don’t know if there is a technical job out there with such a strong degree infrastructure out there where a person without a degree can still shine.
It’s not easy or fast, but it can be done.
