Script Preparation code:

const generateRandomString = () => Math.random().toString(36).substring(7);

// Create the currentList object with a long listElements array
const currentList = {
  field1: generateRandomString(),
  field2: generateRandomString(),
  field3: generateRandomString(),
  listElements: Array.from({ length: 10000 }, () => generateRandomString()),
};
let valuesList = [];
for (let i = 0; i < 100; i++){
  
valuesList[i] = Math.floor(Math.random() * currentList.listElements.length)
}

Tests:

splice check
function spliceOperation() { let innerJ = 0; for (let i = 0 ; i < valuesList.length; i++){ innerJ = valuesList[i]; currentList.listElements.splice(innerJ, 1); } }
splice spread
function sliceSpreadOperation() { let innerJ = 0; for (let i = 0 ; i < valuesList.length; i++){ innerJ = valuesList[i]; currentList.listElements = [ ...currentList.listElements.slice(0, innerJ), ...currentList.listElements.slice(innerJ + 1), ]; } }
