A value that is incremented or decremented and then not stored is at best wasted code and at worst a bug.
Noncompliant code example
function pickNumber() {
let i = 0;
i = i++; // Noncompliant; i is still zero
return i++; // Noncompliant; 0 returned
}
Compliant solution
function pickNumber() {
let i = 0;
i++;
return ++i;
}
