initial-expression	Statement or variable declaration. Typically used to initialize a counter variable. This expression may optionally declare new variables with the `var` keyword.
condition	Evaluated on each pass through the loop. If this condition evaluates to true, the statements in `statements` are performed. This conditional test is optional. If omitted, the condition always evaluates to true.
increment-expression	Generally used to update or increment the counter variable.
statements	Block of statements that are executed as long as condition evaluates to true. This can be a single statement or multiple statements. Although not required, it is good practice to indent these statements from the beginning of the `for` statement.
