Hi all, I’m trying to create a random generator to generate an element of an Array/List. Found this in the docs:
val forBreakfast = Random.nextInt(until = 3).let { menu[it] } I get most parts of this code except for what does ‘it’ mean in the square brackets? Is it some placeholder variable to represent the generated number or something?

above code is equivalent to menu[Random.nextInt(until = 3)]

Ah I see. Thank you!

Documentation specifically about `it`: https://kotlinlang.org/docs/lambdas.html#it-implicit-name-of-a-single-parameter
