#1 What is JavaScript?
Javascript is developed by Netscape . Although it seems close to java because of the name they are far from each other. Javascript is a script language rather than a programming language.
It is written into html pages, making the page more interactive. For example, click events, such as warning messages, make the page more dynamic . What can be done with html pages written without Javascript is limited.
For those who want to become a web developer is a script to learn . Of course, you need to have good html-css information before that. I think it would be enough to separate your 2 days for the html-css duo. There are many html-css trainings that are good on the Internet .
Javascript code is written between the <script> Javascript </ script> tags. They are embedded in the <body> tag within the html page . It can also be written after the <head> tag instead .
Let's finish with a simple example after a short introduction.
1) First let's go through basic html codes.

Open the Notepad ++ or notepad program and type the above codes. From the upper-left corner , select File -> Save As , and save the extension as .html . For example, trial.html
Right click on this .html file and a blank page will appear when you open it in the browser. Because we didn't write anything on the body . In Body , we write what we want to appear on our page. Head tags include the title of our page , import operations, etc. we do.
2) Now let's see how we use our javascript codes. It was a slightly previous plain html page.

We wrote the <script> tags between our body tags and finally closed with </ script> . We write our javascript code between these <script> tags . I've done the print on the screen here. In Javascript, screen printing is printed with document.write () .
We added type = text / javascript to the <script> tag . We've specified that javascript is used here. We also write the <meta charset = 'utf-8'> tag at the head, so that we have a Turkish character shortage.
If we save the code after writing it and run the html extension page again (page refresh can be done) we get the following output.
