Welcome to my totally awesome JavaScript game!

In JavaScript, how do you decrement a variable by 1?

x--
x++
x -= 2

Correct! "x++" increments a variable by 1, and "x -= 2" would assign x the value of x - 2.

What symbol represents "or"?

&&
||
!

Correct! && means "and" while ! means "not".

How do you get back the opposite value from an expression?

Add "-" in front of the expression
Use "/=" in your expression
Use "===" in your expression

Correct! /= is used to assign the value of an operand to itself divided by another operand. === is a strict equals for both value and type.

How do you say that two things are not equal?

x != y
x !== y
both 1 and 2

Correct! != means 2 operands are not equal in value, and !== means they are not equal in value or type.

What does "===" mean?

The operands are not equal
The operands are equal in both value and type
It's no different than "==" but some people like to use 3

Correct! If the value of 2 operands is not equal, you would use "!=". == means 2 operands are equal in value.

How would you compound the operators for a variable that is multiplying itself with another operand?

x *= y
x %= y
x += y

Correct! %= would assign the value of remainder from x divided by y to the x variable, and += would assign the value of x + y.
