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.
function foo() : any { // Noncompliant return 1; }
function foo() { return 1; } // or function foo(): number { return 1; }
