Pattern: Too many returns in method
Issue: -
Restrict the number of return methods allowed in methods.
Having many exit points in a function can be confusing and impacts readability of the code.
Example of incorrect code:
fun foo(i: Int): String {
when (i) {
1 -> return "one"
2 -> return "two"
else -> return "other"
}
}Example of correct code:
fun foo(i: Int): String {
return when (i) {
1 -> "one"
2 -> "two"
else -> "other"
}
}
