Kotlin
Redundant argument-based 'let' call
Info
New
Last modified: 03 December 2024 Reports a redundant argument-based let
call.
let
is redundant when the lambda parameter is only used as a qualifier in a call expression.
If you need to give a name to the qualifying expression, declare a local variable.
Example:
fun splitNumbers() {
"1,2,3".let { it.split(',') }
}
The quick-fix removes the extra let()
call:
fun example() {
"1,2,3".split(',')
}
Alternative:
fun splitNumbers() {
val numbers = "1,2,3"
numbers.split(',')
}
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
