+javascript is dynamically packed language
+don't have to define like other languages, ex just put 5
+
+
+String
+Number
+ int
+ dec -decimal
+ float -many decimals, more specific
+
+variable types: (fixed)
+var
+ var x = 5
+ var x = 10, fixed now x i 10
+
+CONT
+ constant at the top, unchange
+
+let
+ work in certain scope, like in a loop
+ only works inside loop AND NOT outside loop
+ Ex. let x = 5
+ dont have to re delare, re define
+
+Operators
+ + , - , * , / basic math operator
+ ++ incremental operators, increment by 1
+ -- de-increment by 1
+ = assign value
+ == it has the same value, compare
+ === same value and same type
