Raw Strings , how are these different from escaped strings and where should be use these

Question

As per my research,

Kotlin has two types of string literals:-

Escaped strings that may have escaped characters in them .

val s = "Hello ,World\n" +
    "from escaped string\n"+
    "kotlin"

Raw string is delimited by a triple quote ("""), contains no escaping and can contain newlines and any other characters:

val m = """Hello, World
       |from raw string
       |kotlin """.trimMargin()

These strings can be used in multi lines without the need to concatenate each line and an without escaping.

Do we use raw strings only for simplicity and easy implementation or do these offer some better performance in any case?

And are these any other use-cases where we should consider using raw strings?

Answer 1

Your answer is well explained here at this website. I am going to include only essential part of it here.

String in Kotlin can be used in multiple ways as described in the above link. It is purely depends upon the requirement for which to use. If you have extra large string like html page etc then you can go with Raw string delimited by triple quote ("""). And in where you have short strings then you could use Escaped strings.

There is no real performance difference between these but depends upon how much string concatenation you are using while building values in it.
