Benchmark: pushIfNotExist 2

Script Preparation code:

function pushIfNotExist(array, element, key="id"){
  	if (!element) return array;

    const isArray = Array.isArray(element);
    const isElementSet = false;
    const isElementMap = false;

    if (isArray || isElementSet || isElementMap) {
        throw Error(
            "pushIfNotExist : Type of element is invalid. Types array, map or set are not supported."
        );
    }

    const isPrimitive = ["string", "boolean", "number"].includes(typeof element);
    const isElementInArray = isPrimitive
        ? array.includes(element)
        : array.some((elementFromArray) => element[key] === elementFromArray[key]);

    if (isElementInArray) return array;

    array.push(element);
