What are operators?
Operators are action-oriented / transformative characters that do something with values. -

What logical operators do you know?
&& (and), || (or), ! (not)
Logical operators compare values and evaluate to true or false. For instance if x = 4 and y = 6 then: (x < 10 && y > 1) is true. (x == 5 || y == 5) is false. !(x == y) is true.

- What are operators?
Operators do an “operation” to two or more values. For example they can do maths operations between to or more values: 5 + 9; 7 - 2 etc… In this case the “+” and “-” sign are the operators, operating between two values (5 and 9, and 7 and 2) They can also be comparative operators that compare two values to another: 4 < 7; or 13 = 4 + 9. Here the “<” and “=” signs are the operators (note that in the 13 = 4 + 9 equation there is another operator - “+”).

Hi @Travis!
Nice answers 
You’re right, but just to add… operators can also perform an action on just one value. These are the unary operators, for example the NOT operator ! is also a unary operator as well as a logical operator — you’ll learn about some more of them later in the course (e.g. ++ and --).

Hi @Bifin!
Questions 1 and 3
Just to check that you understand what the binary operators are:
true and false are not operators, they are Boolean values (a type of value); but
OR || is a logical operator and a binary operator because it performs an action on two values (true and false in your example).
Other examples of binary operators are:
(i) Arithmetic operators
* multiplied by
/ divided by
% remainder
+ add
- subtract
(ii) Comparison operators
> greater than
< less than
>= greater than or equal to
<= less than or equal to
== equal to (in value)
!= not equal to (in value)

Hi @Kingsman! Great answers 
I’m sure this was just a copy/paste error, but just to confirm that the decrement operator is 2 minus signs -- and not a single dash –

- Operators are symbols that combine values to interact with one another, creating an expression that outputs an absolute value.
2 Binary operators are operators that combine or compare two or more values. A few examples are add (+), subtract (-), multiply (*) and divide (/). - Logical operators are operators that can be applied to Boolean values such as and (&&), or (||), not (!).

Hi @Emmerich!
Some really nice detail here
Just a couple of observations, to help you go even deeper…
In actual fact = is not a comparative operator, but an assignment operator. It doesn’t compare, it assigns e.g. let myVariable = 4 + 9;
Correctly written, your example of a comparative operator should be:
13 == 4 + 9 // equal to (in value) operator
// or
13 === 4 + 9 // strict equality / identical (both value AND type) operator

By the way…
… the NOT operator ! is actually a unary operator, as well as a logical operator (it’s not a binary operator). Unary operators perform an action on just one value (which can also be an expression). You’ll learn about some more of them later in the course (e.g. ++ and -- ).

Nice answers @AF90!
I can see you’ve put a lot of thought into the concepts
Just one thing to clarify…
… only two values (before and after). There is also something called a ternary operator that performs an action on 3 values. Look it up if you haven’t heard of it… it’s pretty cool

Haha yeah, not sure how I got to that. I think I was a little tired after taking in all the info in chapter 1 and rushed these answers.
