Consider a scenario with nested ternary statements:
return foo ? 1 : bar ? 2 : 3;
How can we effectively format this code for better readability by future viewers?

I found the top-rated answer which offers a helpful solution. The recommended approach is:
return condition1 ? value1 :
condition2 ? value2 :
value3 ;
My choice leans towards the clarity of this particular format for ternary operators:
prefer foo
? use bar
: utilize baz
? select qux
: pick qiz
? choose 1
: opt for 2;
if (foo) {
return 1;
} else if (bar) {
return 2;
} else {
return 3;
}
Breaking down into different functions
function determineValue(condition1, condition2) {
if(condition1) return 'apple';
if(condition2) return 'banana';
return 'carrot';
}
function performTask() {
const output = determineValue(/* specific conditions */);
}
It's difficult to determine if this approach is widely accepted, but personally I find it very useful and use it frequently.
The ternary operator provides a simple testing structure that enhances code readability when used in multiple lines with proper indentation. I am convinced that utilizing the ternary operator in a nested conditional format is one of the most effective ways to write code.
return foo ? 1
: bar ? 2
: 3;
In more complex scenarios, combining the ternary operator with the comma operator can result in elegant solutions. Remember that the last statement in a comma-separated group will be automatically returned, making it particularly convenient for ternary operations.
return foo ? ( doSomethingFoo()
, variable++
, collectResult() // return foo result
)
: bar ? ( doSomethingBar()
, variable--
, collectAnotherResult() // return bar result
)
: ( doSomethingReject()
, variable = 0
, rejectSomehow() // return error code
)
Avoid using complicated statements that can be easily misinterpreted for better readability. Instead, opt for clearer and more straightforward expressions.
There's no harm in utilizing a nested if statement list for improved clarity.
if(foo){
return 1
}else{
if(bar){
return 2;
}else{
return 3;
}
}
