My code is in strict mode, and I am encountering an issue with the following snippet:
const a: string[] = [];
// logic to populate `a`
while (a.length > 0) {
const i: string = a.pop(); // This line is causing an error
console.log(i);
// additional operations on `a`
}
The error arises from the fact that the pop method has a return type of string | null. Although this is expected behavior for general use of pop, I need to address this specific case. Is there a more TypeScript-optimized approach to handle this typeguard situation?
Unfortunately, simply iterating over the array using of is not feasible because new elements are sometimes added to a during the loop, leading to altered semantics.
