Example of making a batch JSON-RPC request and concisely destructuring the response by (ab)using the JSON-RPC id as the variable name.

batchJsonRpcDestructure.js

const rpc = 'https://ethereum.publicnode.com';
const to = '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48';
const requests = {
  name: '0x06fdde03',
  symbol: '0x95d89b41',
  decimals: '0x313ce567',
  totalSupply: '0x18160ddd'
}
const payload = [];
for (const [id, data] of Object.entries(requests)) {
  payload.push({
    jsonrpc: '2.0',
    id,
    method: 'eth_call',
    params: [{ to, data }, 'safe']
  });
}

const response = await fetch(rpc, {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify(payload)
}).then(r => r.json());

// These values still must be ABI decoded
const { name, symbol, decimals, totalSupply } = response.reduce((a, c) => ({ ...a, [c.id]: c.result }), {});
