Control flow allows you to direct the flow of code depending on the conditions which are given. Here are the main operators used in comparison evaluations.
4 > 10 // false
'hi' > 'hello' // true, checks if greater alphabetically
4 >= 3 // true
The difference between the first two conditionals can be show by a simple example:
3 == '3' // true
3 === '3' // false, must be of same type
3 != 3 // false
The logical operators AND or OR allow you to group two evaluations together. An AND evaluates to true only if both sides of the expression are true, while an OR evaluates to true if either side is true.
To get the opposite of an evaluation, use the exclamation mark (!). This will turn a false into true and vice versa.
!true; // false
! (3 > 3) // true
4 < 3 && 2 < 5; // true
true || false // true
