Comparing the Same Project in Rust, Haskell, C++, Python, Scala and OCaml

Usually it's awful. I wish JavaScript had if else expressions. Sometimes it can help to break up the lines with indents if you need a single expression:

  var myvar = foo < bar
    ? bar
    : bar < baz
      ? baz
      : 0

I settled on this a while ago which I think is perfectly readable:

    const myvar
      = foo < bar ? bar
      : bar < baz ? baz
      : lark < 10 ? lark
      : 0

Your wish can come true. Take a look at this stage 1 of the TC39 proposal. https://github.com/tc39/proposal-do-expressions

I would format that as either:

  var myvar =
    foo < bar ? bar :
    bar < baz ? baz :
                0

or:

  var myvar =
     foo < bar ? bar
   : bar < baz ? baz
   : 0
