Example
In Kotlin strings are compared with == operator which chect for their structural equality.
val str1 = "Hello, World!"
val str2 = "Hello," + " World!"
println(str1 == str2) // Prints true
Referential equality is checked with === operator.
val str1 = """
|Hello, World!
""".trimMargin()
val str2 = """
#Hello, World!
""".trimMargin("#")
val str3 = str1
println(str1 == str2) // Prints true
println(str1 === str2) // Prints false
println(str1 === str3) // Prints true
