The return type any
should be avoided because it prevents the type safety checks normally done by the compiler. When a function
returns a primitive type (i.e. number, string or boolean) it is safe to replace any
with number
, string
or
boolean
type respectively, or remove the return type completely and let compiler infer it.
Noncompliant code example
function foo() : any { // Noncompliant
return 1;
}
Compliant solution
function foo() {
return 1;
}
// or
function foo(): number {
return 1;
}
