当作为一个构造函数(带有运算符 new)调用时,Boolean() 将把它的参数转换成一个布尔值,并且返回一个包含该值的 Boolean 对象。 如果作为一个函数(不带有运算符 new)调用时,Boolean() 只将把它的参数转换成一个原始的布尔值,并且返回这个值,如果省略 value 参数,或者设置为0、-0、null、""、false、undefined...
If you add two numbers, the result will be a number:Example let x = 10; let y = 20; let z = x + y; Try it Yourself » If you add two strings, the result will be a string concatenation:Example let x = "10"; let y = "20"; let z = x + y; Try it Yourself »...
上面代码中,array.push(…items)和add(…numbers)这两行,都是函数的调用,它们都使用了扩展运算符,该运算将一个数组,变为参数序列。 扩展运算符与正常的函数参数可以结合使用,非常灵活。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 function f(z, x, c, v) {} var args = [0, 1]; f(-1, ...
