AND is to check TRUE two conditions Example: if (a>10 and a<15) if both conditions are TRUE then result is TRUE and in that example 'a' is a number between 11 and 14 but if some or both are FALSE then result is FALSE

NOT is to check "negative" condition. Example: If (not (a>10)) If a=5 then not(5>10)=not(false)=TRUE If a=11 then not(11>10)=not(true)=FALSE

OR is to check TRUE one or both conditions. Example: if (a>10 or a<15) if both conditions are TRUE then result is TRUE, if a>10 and not a<15 then result is TRUE and 'a' could be a number from 15 to infinite, if not a>10 and yes a<15 then result is TRUE and 'a' could be a number from 10 to minus infinite. Of course if both conditions are FALSE then result is FALSE

Ok and what about the "NOT" one? It says "if the operand is false,and false,if the operand is true" what does that mean?

example for NOT: x= 3, y=5; if( x!== y) // 3 not 5 = true { /* do something*/ } (x !== y) is same as (3 NOT 5) and its True because 3 not equal 5

in js use : "&&" as "AND" operator, "||" as "OR" operator, "!" as "NOT" operator
