Automatic Semicolon Insertion

Anywhere the syntax parser expect that semicolon will be, it will put one for you, that why semicolons seems optional, as you’re writing the code, you should always put your own semicolons, also, automatic semicolon insertion could cause big problem

by avoid this mistake, you should always put curly brackets on the same line as functions, for loops and if statements etc. instead of put them one the newline.
