@Alejandro Serrano Mena there are some small errors in the code examples in https://www.47deg.com/blog/arrow-analysis-kotlin-compiler-plugin/ • In the examples with the extension functions on

List<Int>

the dot is missing between the receiver type and the function name • In the second extension function,

fun List<Int>.firstOrZero()

using

isNotEmpty()

the logic is the other way around (should be

if (this.isNotEmpty()) this.first() else 0

)

thanks for catching this 👍

👍

solved!

Looks good, but now the description of the function using

isEmpty()

has to be adjusted as well (2 lines above it still mentions

isNotEmpty()

) 😉
