Script Preparation code:

var contracts = [{
        address: "0xD4933879BaC3F7f76AADC6395650f41553d6aaaa",
        tokenIds: [],
    },

];

var arr1 = [];
var arr2 = [];
var arr3 = [];
var arr4 = [];

function predicate(el) {
    return el.tokenId.length === 0;
}

Tests:

foreach
contracts.forEach((element) => (element.tokenIds.length ? arr1.push(element) : arr2.push(element)));
reduce
contracts.reduce( (acc, element) => { acc[element.tokenIds.length ? 0 : 1].push(element); return acc; }, [[], []] );
two filters
arr3 = contracts.filter(f => f.tokenIds.length); arr4 = contracts.filter(f => !f.tokenIds.length);
