To my personal taste, a carefully aligned nested ternary beats the if-else mess:
const H =
C == 0 ? null :
V == r ? (g - b) / C :
V == g ? (b - r) / C + 2 :
(r - g) / C + 4 ;

I think you can have this to avoid the deep nesting:
var H
if(C == 0){
H = null;
}
else if(V == r){
H = (g - b) / C;
}
else if (V == g){
H = (b - r) / C + 2;
}
else {
H = (r - g) / C + 4;
}

r/learnjavascript on Reddit: Nested ternary operators!!
January 19, 2025 -
Hi
I never use ternary operators, but I'm willing to learn and give it a shot for my next personal project.
My question is, i confused myself now trying to do a nested ternary operator.
For example a typical ifelse nested statement looks like this
if (example1 === 1) {
if (example2 === 2) {
console.log("yes")
}
else if (example2 === 3 {
console.log("no")
}
else {
return example3
}else if (example2 === 2) {
if (example 3 === 3) {
console.log("yes")
}
else {
return example3
}else {
console.log ("i know this example suck")
}
how do i do the exact nesting in ternary operators, i googled but got more confused.

Statements , like return ... (the "return statement"), cannot be placed inside ternary operators — only expressions can be placed inside the ternary operator. Therefore, this code cannot be changed to use ternary operators.

Your code was messed up, so I took some guesses to fix it. if (example1 === 1) { if (example2 === 2) { console.log("yes"); } else if (example2 === 3) { console.log("no"); } else { return example3; } } else if (example2 === 2) { if (example 3 === 3) { console.log("yes"); } else { return example3; } } else { console.log ("i know this example suck"); } You can have expressions (but not returns) within a ternary. A ternary expression returns a value, so is generally used to return a value with some conditional branches, as one statement. In keeping with that, I'll change the if statement version to this: var result; if (example1 === 1) { if (example2 === 2) { result = "yes"; } else if (example2 === 3) { result = "no"; } else { return example3; } } else if (example2 === 2) { if (example 3 === 3) { result = "yes2"; } else { return example3; } } else { result = "final"; } You can replace features of an if statement with the equivalent from a ternary. And you can use newlines just fine, and even brackets to help you visualise the structure. ...

I always prefer using if statements, they have a nice structure to them and are very intuitive if you use {} and indent each nested if. ... it’s also good to space out the binary operators like necro did. I actually space out after the parenthesis too. if ( i < n ) { etc etc ... I am learning JavaScript right now, but if my memory serves correctly for C# you cannot use ternary operators for nested if statments.
