just for readibility i would move these functions after maxRank

applyWithChunking first, followed by splitToChunks.

since we are not using const myFn = () => {} we can get away with this and makes it easier to read

const chunks = [];
for (let i = 0; i < array.length; i += chunkSize) {
const chunk = array.slice(i, i + chunkSize);
chunks.push(chunk);
}
return chunks;
}

const CHUNKING_THRESHOLD = 65535;

function applyWithChunking(fn, argsArray) {
if(argsArray.length > CHUNKING_THRESHOLD) {
const chunks = splitToChunks(argsArray);
return fn.apply(null, chunks.map(chunk => fn.apply(null, chunk)));
} else {
return fn.apply(null, argsArray);
}
}

function maxRank(g) {
return Math.max(...g.nodes().map(v => {
const nodes = g.nodes();
const nodeRanks = nodes.map(v => {
let rank = g.node(v).rank;
if (rank === undefined) {
return Number.MIN_VALUE;
}

return rank;
}));
});

return applyWithChunking(Math.max, nodeRanks);
}
