var a=100; document. write(a);

Here is how to declare them(they are declared with 'var')

Variables are special places to store to store data by declaring it first or after storing a data in it. It is unusual and non working pre-declaration of variable in JavaScript.

#variables.... . . . .

By the way we will pass on #C++ after we finish JavaScript.

Okay bro I showed some basics. But I am going pass to variable. I only show u basics work on the details by ur self.

Spacing spacing is not big issue in many cases Example window.alert("hi"); And window.alert ("hi"); are the same spacing inside the brackets or braces have so much change.

Case sensitive That means in JavaScript ball and Ball are two different things .(u can see here that JavaScript is unlike HTML since HTML is case sensitive)

Semi colon (;) are the symbols to end a statement but are not much necessary in JavaScript if u are writing the code statement on separated lines. example... var a=10; var b=30; The above statement is the same as var a=10 var b=30 How ever if u need to write the code on the same line u must put the semicolon as the following var a=10;var b=30;

Today we will finish #syntax and and or and ready for JavaScript #variable

Enabling JavaScript If u still couldn't launch JavaScript .... Go to setting of the browser the click on "advanced" then tick on "Enable JavaScript"or simply"script" and "JavaScript"

That is all for today brothers
