Nesting ternary operators makes code more complex and less clear. Let's investigate other ways to write conditional expressions.

    Until JS supports switch expressions, nested ternaries will continue to be the most effective way to write multi-state conditionals.

    Also, stop using linting tools that prioritize consistency over human readability, and then complaining that the code they generate is not easily-readable by humans.

          Your probably right, that looks quite desirable.

          they also said switch expressions, which indicates they want the switch statement to be settable directly to a variable with whatever the return type of the switch is.

            Match already returns the value which can be thrown into a variable.

          Nah, I meant switch, as that’s what it’s called in C#-land. See above.

          That proposal for matching looks interesting, but not quite the same, no.

            Are you sure?

            Your C# example:

            var output = input switch
{
    null    => "Null",
    0       => "Zero",
    > 0     => "Positive",
    _       => "Negative"
};

            JS proposal for match:

            const output = match input {
    when null:    "Null";
    when 0:       "Zero";
    if input > 0: "Positive";
    default:      "Negative";
}

        Yeah, a switch expression is different than a switch statement. I’m not actually sure how many languages actually have them, but in C# its…

        var output = input switch
{
    null    => "Null",
    0       => "Zero",
    > 0     => "Positive",
    _       => "Negative"
};
