用来表示当前函数传入的参数,作为伪数组输出(可通过 Array.from 转换成数组) 示例: functiontotal(x, y =2, z =3) {returnarguments}console.log(total(1)) 输出: 通过以上代码可知,默认参数不存在 arguments 中 functiontotal(x, y =2, z =3) {returnarguments.l
五、Rest parameter 获取函数中被执行的参数 代码语言:javascript 代码运行次数:0 运行 AI代码解释 functiontotal(...num){letcount=0num.forEach(item=>{count+=item*1})returncount}console.log(total(1,2,3,4))// 10 也可以独立出某个参数,例如: ...
在js性能测试中总结了,在测试方法中使用命名参数访问效率要比使用arguments对象快到2-8倍。具体优化的速度可能取决于函数具体的实现,但是arguments对象的效率显然是偏低的。 Optimization killers Is it a bad practice to access the arguments object to every function that takes parameters? 剩余参数(Rest Parameter)...
