operator precedent in javascript
Brackets pOwers (Division Multiple) (Addition Subtraction)

modulas operators give you the remainder (whatever is left) of any division
first it divides what it can
ie: 5 goes into 9 once with 4 left over
9 % 5 = 4
10 % 2 = 0 (there is nothing left over from the division)
modulas is good for finding odd or even numbers


+= 30
add to the existing values

-= 20
subtract from the existing values

*= 2
multiple existing values

/= 4
divide existing values

%= 4
modulas existing values

**= 4
"to the power of (4 x existing value 4 times)" existing values

the plus + operator also deals with strings
"string" + "string" = stringstring

polymorphism is like playdo.. it adapts to whatever shape you need
"string" + 10 = string10
