Benchmark: Move to First New

Script Preparation code:

var wallets = [
  {
    currency: {
      id: "USD"
    }
  },
  {
    currency: {
      id: "IDR"
    }
  },
  {
    currency: {
      id: "SGD"
    }
  },
]

Tests:

Original Code
const moveCurrencyToFirst = (wallets, currencyId) => { const currencyIdx = wallets.findIndex( (wallet) => wallet.currency.id === currencyId ); const tempWallets = [...wallets]; if (currencyIdx !== -1) { const currWallet = wallets[currencyIdx]; tempWallets.splice(currencyIdx); tempWallets.unshift(currWallet); } return tempWallets; }; console.log(moveCurrencyToFirst(wallets, "SGD"))
New Code
const moveCurrencyToFirst = (wallets, currencyId) => { const selectedWallet = wallets.find( (wallet) => wallet.currency.id === currencyId ); let result = wallets.filter( (wallet) => wallet.currency.id !== currencyId ); if (selectedWallet) { result = [selectedWallet, ...result]; } return result; }; console.log(moveCurrencyToFirst(wallets, "SGD"))
