Common JavaScript Manual/Data types - Numbers

Numbers
For example, let's set the value for the variable 'a' And for the variable 'b'

Arithmetic operations
Let's output results of arithmetic operations with these variables.

Increment, Decrement, Unary operators
For enlarging or reducing some variable by one we can use increment and decrement operator. And we can change char of number by unary operator. Decrement and increment have two types of recording - postfix and prefix. Prefix - first the value is changed then the new value is returned. Postfix - first the value is returned then value is changed.

Standart library functions
