Check if a string is number or not usingNumber()function. If the string is number then convert Number() returns the numeric value orNaN(Not a Number). We will take a sample typescript string and convert it to number. varstringToConvert ="759";varnumberValue =Number(stringToConvert);cons...
function convertStringToNumber(input: string): number {// 实现自定义的字符串转数字逻辑return parseFloat(input);}const stringValue: string = "3.14";const numberValue: number = convertStringToNumber(stringValue); 在上述代码中,我们定义了一个名为convertStringToNumber的函数,用于将字符串转换为数字。通过自...
AI代码解释 importmomentfrom'moment';constdateString='2022-05-30';constdateObject=moment(dateString).toDate(); 在上面的代码中,我们首先使用 import 语句导入 moment.js 库,然后声明了一个日期字符串dateString。接着,我们使用 moment 函数将日期字符串转换为 moment.js 对象。最后,我们使用 toDate 方法将 mome...
而在 TypeScript 中，也可以相应地表达不同类型的参数和返回值的函数，如下代码所示：function convert(x: string | number | null): string | number | -1 {if (typeof x === 'string') {return Number(x);}if (typeof x === 'number') {return String(x);}return -1;}const x1 = convert('...
