List of all binary operators in JavaScript

Question

I am trying to understand what is possible with binary operators (only binary operators) in JavaScript. So far the list of binary operators I have discovered are the the following. They are primarily sourced from this list, but are any missing?

Note, I am after specifically only binary operators which, according to the source listed above, is defined as binary operators you use with two objects (is this accurate?). I have also added the additions from @zessx.

+   //Add
-   //Subtract
/   //Divided by
*   //Multiple
%   //Modulus
<   //Less than
>   //Greater than
&   //AND
|   //OR
^   //XOR
~   //Invert each bits
<<  //Move all bits onto the left
>>  //Move all bits onto the right
>>> //Move all bits onto the right and fill left end with 0

there are also binary operator for bit, like '|' (or) and '&' for and. — YS., Aug 25 '12 at 13:19

this seems to be a video guide of all operators: http://bateru.com/news/2011/03/javascript-binary-operations-the-easy-way/ — Marcelo De Zen, Aug 25 '12 at 13:21
Really not sure why this is getting down voted. I am sure it is for a good reason, but I am really not sure why. — fakeguybrushthreepwood, Aug 25 '12 at 13:44
@u1sonderzug Because this information is so prevalent on the internet. Just google it. — Lee Taylor, Aug 25 '12 at 13:51
I understand finding lists of operators on Google, etc is relatively straight forward but I am specifically trying to understand which one of them are binary operators. It's just a term I learnt recently so still working out what precisely a binary operator is. — fakeguybrushthreepwood, Aug 25 '12 at 14:00

You will find a complete list in the specification, in the expression chapter. Because the most "normal" operators are binary (see the definition at Wikipedia), they are not explicitly listed as such (like the unary and ternary operators). They are:

Multiplicative Operators
- The * Operator
- The / Operator
- The % Operator
Additive Operators
- The Addition operator (+)
- The Subtraction Operator (-)
Bitwise Shift Operators
- The Left Shift Operator (<<)
- The Signed Right Shift Operator (>>)
- The Unsigned Right Shift Operator (>>>)
Relational Operators
- The Less-than Operator (<)
- The Greater-than Operator (>)
- The Less-than-or-equal Operator (<=)
- The Greater-than-or-equal Operator (>=)
- The instanceof operator
- The in operator
Equality Operators
- The Equals Operator (==)
- The Does-not-equals Operator (!=)
- The Strict Equals Operator (===)
- The Strict Does-not-equal Operator (!==)
Binary Bitwise Operators (&, ^, |)
Binary Logical Operators (&&, ||)

Technically speaking, also the assignment and comma operators are binary.

There are the following arithmetic operators supported by the JavaScript language.

Assume variable A holds 10 and variable B holds 20 then:

The conditional expression (also called "*the* ternary operator") is *not* a binary operator. – Bergi Aug 25 '12 at 13:40
@Bergi The question was modified after this post. Originally it was talking about all operators. – Lee Taylor Aug 25 '12 at 13:50
OK, but then you forgot all those unary operators like `!` or `new`… – Bergi Aug 25 '12 at 14:02
