Within the for loop we have three statements - We declare the variable, we set the condition and we add the increment to the variable. Why don't we put a semicolon at the end of the increment statement like the other two statement?
for ( var i = 1 ; i <= 10 ; i += 1 (why isn't there a semicolon here )){
}

The parts of a for loop aren't actually statements.
The for loop takes three optional expressions, enclosed in parentheses and separated by semicolons. Since the semicolons only separate the expressions from each other, only two are required.
A third one would be interpreted as a separator for a fourth (omitted) expression, which would not be proper syntax.
