in

val A = StringBuilder(string = "")
val B = StringBuilder(content = "")

what is the difference between string and content, like do both do the exact same thing?

[tddmonkey]

I don’t see a constructor with that signature

[Shawn]

it’s documented on this page: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/-string-builder/

[Shawn]

but looking at the definition on my machine (Kotlin/JVM) it’s just a typealias for the java stringbuilder, which doesn’t define a content param

[tddmonkey]

Unless I’m missing something I still don’t see a constructor takes 2 strings called content and string

[Shawn A]

Looks like its for Kotlin/js?

[Smallville7123]

val A = StringBuilder(string = "")
val B = StringBuilder(content = "")

[Shawn]

ahh, I think that might be what it is

[Shawn]

there’s a StringBuilder ctor that takes a CharSequence called content that’s on Common, though

[Shawn]

StringBuilder(content: String) is just a JS thing it looks like

[Shawn]

StringBuilder(content: CharSequence)
StringBuilder(string: String)

for everyone else

[Shawn A]

I've been confused more than a few times by the inclusion of js stuff in the docs.

[Shawn]

yeah, I personally only use kotlin/jvm so the docs have definitely tripped me up ’cause I forget to look at the indicators

[Smallville7123]

but whats the difference between the two

[Shawn]

One constructor takes a CharSequence, the other a String

[Smallville7123]

other than their types

[Smallville7123]

as if they are named differently then they gotta to something different right?

[Shawn]

I mean, the CharSequence ctor probably just, does whatever it needs to do to load the chars in the CharSequence into whatever mechanism stores string data

[Shawn]

maybe that’s a conversion to String?

[Shawn]

the parameters are named differently likely because, well, you don’t want to call a CharSequence that isn’t necessarily a String, string

[Shawn]

content is a fine, more generic name

[Smallville7123]

then why not name both as content lol

[Shawn]

convention, probably

[Shawn]

the java ctor takes a param named str, string is a natural extension of that

[Smallville7123]

ok lol

[Shawn]

the content param makes it noticeable that that constructor takes in not String, but instead anything that implements CharSequence

[Smallville7123]

what does ensureCapacity do

[Shawn]

“lol”

[Shawn]

I’m not sure, tbh, it’s not documented and only available on Native

[Shawn]

Are you writing K/N?

[Smallville7123]

yes

[Shawn]

It may be an allocation thing, but you might be better served asking nicely in #C3SGXARS6

[Smallville7123]

ok

[karelpeeters]

Java has it too, I'm not sure why they didn't include that in the Kotlin version.
