The conditional (ternary) operator is the only JavaScript operator that takes three operands: a condition followed by a question mark (?), then an expression to execute if the condition is truthy followed by a colon (:), and finally the expression to execute if the condition is falsy.

Javascript ternary operator and assignment
It works perfectly: > var t = 1 == 1 ? 1 : 0; undefined. > t. 1. You could say that the return value of the assignment operation is undefined, not the value of t. Edit: But actually if I read the specification correctly, it seems that it should return the value of the expression. As @T.J. Crowder mentioned, it seems the var is responsible for ...
How to Use the Ternary Operator in JavaScript
Inside the function, we use the ternary operator to check if the number is even or odd. If the number modulo 2 equals 0 (meaning it's divisible by 2 with no remainder), then the condition evaluates to true, and the string "even" is assigned to the result variable. If the condition evaluates to false (meaning the number is odd), the string "odd ...

Expressions and operators
This chapter describes JavaScript's expressions and operators, including assignment, comparison, arithmetic, bitwise, logical, string, ternary and more. At a high level, an expression is a valid unit of code that resolves to a value. There are two types of expressions: those that have side effects (such as assigning values) and those that ...
variable assignment
The important thing to realise with the ternary operator in this and other languages is that whatever code is in <expression> should produce a boolean result when evaluated: either true or false. In the case of your example replace "assigned to" in my explanation with "added to", or similar for whichever shorthand arithmetic you are using, if any.
