1 minute read


I scream that it will be a little bit strange. Maybe everyone reading this You’ve probably heard about it.

It says from conclusion

Java and JavaScript are different! !! !!

Why am I making a mistake

If you simply put it away as “lack of study” It’s easy For some reason, stubbornly call JavaScript “Java” There are a lot of people who say something.

Why this happens

The language itself called JavaScript With Sun Microsystems, which was involved in Java development Because it was a developed language

But come on

Yeah, I understand, I know that feeling If you’re an IT engineer in Homma, this is the difference It’s natural to understand.

Some people still don’t understand

why! !! I think it’s common sense in IT People who are not familiar with IT in the first place are in the IT industry There is a certain number. (That’s funny)

Big misunderstanding due to paid Java

Originally, in the workplace There was an application that used “JavaScript”. When Java is paid In utilizing the above apps It will be paid, but is it okay? I received a question such as.

Case premise

At the stage of requirement definition and specification Already refused not to use Java

Is it a literacy issue?

Still, because it contains “Java” What you misunderstood Some people often ask me questions. I just have to study this much.

People called engineers in Japan

Probably I think people who study every day. Be sure to catch up with new information It’s important for engineers to evolve think.

If you say something like an extremist Otherwise you are not an engineer. Even if some people call themselves engineers If it’s out of my definition I am not standing on the same ring as myself. I think so.
