Tests:

Splice
function removeRequestsByIndices(indices) { // Sort indices in descending order to avoid re-indexing issues when splicing indices.sort((a, b) => b - a); // Remove each request at the specified index indices.forEach(index => { if (index >= 0 && index < persistedRequests1.length) { persistedRequests1.splice(index, 1); } }); } removeRequestsByIndices(indicesG);
Set-Filter
function removeRequestsByIndices(indices) { // Create a Set from the indices array for efficient lookup const indicesSet = new Set(indices); // Create a new array excluding elements at the specified indices persistedRequests2 = persistedRequests2.filter((_, index) => !indicesSet.has(index)); } removeRequestsByIndices(indicesG);
Set-Loop
function removeRequestsByIndices(indices) { // Convert indices to a Set for faster lookup const indicesSet = new Set(indices); const newPersistedRequests = []; // Iterate over persistedRequests and build a new array excluding the specified indices for (let i = 0; i < persistedRequests3.length; i++) { if (!indicesSet.has(i)) { newPersistedRequests.push(persistedRequests3[i]); } } // Update the persisted requests persistedRequests3 = newPersistedRequests; } removeRequestsByIndices(indicesG);
