Yesterday, we looked at how to create a formatted string from a number with the Intl.NumberFormat API. Today, we’re going to learn how to use that same API to format currency. Let’s dig in! (If you haven’t yet, go read yesterday’s article first or th
typeof cur === "string" && acc.push(cur); return acc; }, []); console.log(newArr);//[ 'March', 'Jan', 'A', 'a' ] //使用reduce实现数字的求和 //第二个参数默认定义0 number类型 const newArr = arr.reduce((acc, cur, index) => { typeof cur === "number" && (acc += ...
在上面的示例中,我们创建了一个名为convertCurrency的函数来执行货币转换操作。该函数接受三个参数:金额(amount),转换前的货币代码(fromCurrency)和转换后的货币代码(toCurrency)。函数内部使用一个固定的汇率值(0.85)来执行货币转换计算,并返回转换后的金额。在示例中,我们将100美元(USD)转换为欧元(EUR),并将转换后...
