Fun poll. Which version do you guys prefer? I just found myself writing the first version without thinking about it, but then wondered why I didn't write the second version. Then after typing out version 2, I couldn't decide which was actually clearer to read. Use the emoji's to vote, and the thread to discuss 🙂 1️⃣

var headerReducer = (headers) => {
	return headers.reduce( ( list, header)=>{
		list = list.listAppend( "#header.name#: #header.value#", chr(13) & chr(10) );
		return list;
	}, '' );
};

2️⃣

var headerReducer = (headers) =>
    headers.reduce( ( list, header) =>
        list.listAppend( "#header.name#: #header.value#", chr(13) & chr(10) ), '' );

for this example I'd always go with using body. the only time I do not use bodies is when its a one liner

firstheader = (headers) => headers.first()

For me 1️⃣ just makes it easier to read... the extra brackets and structure help me to more quickly visualize what is going on.. it's just how my brain works

Yeah, I was curious how much of my preference was my my bias for what I'm used to reading. I'm curious what JS-heavy people normally do here.

I certainly have a heavy JS influence in my cfscript choices

I would say the preferred way in angular and nextjs communities is to do 1️⃣ for multiple lines and 2️⃣ for single lines. But now that this is my 2nd time looking at your example I would agree that 2️⃣ is easy to ready.

list.listAppend( header.name & ": " & header.value, .. )

🙂

& that too lol

Heh, yes. That function was a copy of another that reduced E-mail addresses with

list.listAppend( "#address.emailAddress.name# <#address.emailAddress.address#>", ', ' )

and I thought that more readable than

list.listAppend( address.emailAddress.name & ' <' & address.emailAddress.address & '>', ', ' )

Once I get to a point where I'm concatenating enough strings, I'll go back to string interpolation usually.
