What is Javascript ?

Javacript is interpreted programming language, which at the beginning, mostly used as the scripting language for Web pages. But since the appearance of nodejs, many non-browser environments can also use it (such as on server), thus it is becoming very popular language.

Few important things about javascript:

  • It is single threaded, you will meet async / callback / promise if you dig deeper.
  • The most popular javascript engine is V8 (Chrome V8), if you using chrome-based browser, then you're already using it.

Sample of Javascript Script :

var a = "hello";
var b = " world";

What is Minification (from Minifier) ?

Minification is the process of removing all unnecessary characters from the source codes without changing their functionality or behaviour. So, the size of your code will be reduced without changing the result of the code.

Minification can remove few things from source code such as spaces and newlines. Or even can change the structure of the code while maintaining the same result (this example is quite extreme, but possible. The process can be quite the same as in the compiler).

The drawback of minification of course the code can be harder to read, thats why minify can be called uglify.
