Benchmark: Move To First - MeasureThat.net

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"))
Updated Code
const moveCurrencyToFirst = (wallets, currencyId) => { const moveToFirst = wallets.find( (wallet) => wallet.currency.id === currencyId ); if(!moveToFirst) return wallets; const rest = wallets.filter( (wallet) => wallet.currency.id !== currencyId ); return [ moveToFirst, ...rest ]; }; console.log(moveCurrencyToFirst(wallets, "SGD"))
