Marking a variable that is unchanged after initialization const is an indication to future maintainers that "no this isn't updated,
and it's not supposed to be". const should be used in these situations in the interests of code clarity.
function seek(input) {
let target = 32; // Noncompliant
for (let i of input) {
if (i == target) {
return true;
}
}
return false;
}
function seek(input) {
const target = 32;
for (let i of input) {
if (i == target) {
return true;
}
}
return false;
}
