Benchmark: FP vs OOP formatting implementation

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

const input = {
    price: '1234.567890'
};
const locale = 'en-US';
const options = {
    style: 'currency',
    currency: 'USD'
};

window.benchmarkConfig = {
    input,
    locale,
    options
}

Tests:

OOP
class BaseFormatter { constructor(locale) { this.locale = locale; } formatPrice(input, options) { const rawValue = parseFloat(input); const formatter = new Intl.NumberFormat(this.locale, options); return formatter.format(rawValue); } } class OrderBookFormatter extends BaseFormatter { format(input) { return { price: this.formatPrice(input.price, window.benchmarkConfig.options), }; } } const oopFormatter = new OrderBookFormatter(window.benchmarkConfig.locale); oopFormatter.format(window.benchmarkConfig.input)
FP
const formatPrice = (input, { locale, options }) => { const rawValue = parseFloat(input); const formatter = new Intl.NumberFormat(locale, options); return formatter.format(rawValue); }; const createOrderBookFormatter = (locale) => { return (input) => { return { price: formatPrice(input.price, { locale, options: window.benchmarkConfig.options }), }; }; }; const fpFormatter = createOrderBookFormatter(window.benchmarkConfig.locale); fpFormatter(window.benchmarkConfig.input)
