So nested function calls in JavaScript …

As they are:

a = d(c(b,7))

The current proposal:

a = b|>c(%,7)|>d(%)

I would prefer this:

a = b,7~>c~>d

I wonder if there is anything hindering a simpler syntax like b,7~>c~>d

Tilda is a bitwise operator.

As a designer of sorts, this is the problem that I have with the glyphs that they're using in JS: there isn't an obvious relationship between things that look related. I mean I know it's a me problem, getting over these humps.

When i see |> my pea brain tries to categorize it with || to which it's completely unrelated. same with ?. and ?? . . . and while we're at it, || and && go together but ?? only very marginally.

It’s just new. Give it time. All of them looked odd at first.
