The bitwise operations and, or, and xor are familiar to most developers. The only difference between them and their logical counterparts is that they do not short-circuit. - Kotlin Cookbook

Does anyone can explain what does the short-circuit means ?

[Jaymin.Kim]

fun foo() = false
fun boo() = { print("boo!"); true }
print("a = ")
foo() && boo()
print("\nb = ")
foo() and boo()

result:

a =
b = boo!

&& is short-circuit.
this means, foo() is false, so boo() don't need to call. so skipped.
and is not short-circuit.
even foo() is false, boo() will call.

This only works for Boolean
