在JavaScript中,return语句通常用于从函数中返回一个值。然而,有时我们需要从一个函数中返回多个值。有几种方法可以实现这一点: 1. 使用数组 你可以将多个值放入一个数组中,然后返回这个数组。 代码语言:txt 复制 function getMultipleValues() { let value1 = 10; let value2 = "Hello"; return [value1, ...
It wouldn’t sound too obvious but sometimes your function might need to return multiple values. For instance, in one of the applications I’m working on, I have a JavaScript function where I have to calculate two different values and return them. So, I needed to return two values from ...
functionmultipleValues(){letvalue1="Hello";letvalue2="World";returnvalue1,value2;} 1. 2. 3. 4. 5. 以上就是实现“JavaScript return 中逗号”的完整代码。 4. 代码解释 在上面的代码中,我们创建了一个函数multipleValues,该函数返回两个字符串值。在函数体内,我们定义了两个变量value1和value2,并将它...

Function with Return Multiple Values A function can also return multiple values. For example, func checkMarks() -> (String, Int) { ... return (message, marks) } Here, the return statement returns two values: message and marks. Also, -> (String, Int) specifies the return type message ...

return values[position]; } } public bool MoveNext() { if (position != values.Length) { position++; } return position < values.Length; } public void Reset() { position = -1; } } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.
Abandoning return values Modern promise-based or event-driven JavaScript no longer uses returned values. Have you noticed the following weird fact: as you get better at JavaScript, your code has fewer and fewer returned values? Remember your initial procedural code: 12345 function foo() { r...
This is useful to run in parallel multiple functions and have control on the returned values. Channelify uses go routines to parallelize the execution of the functions. The idea comes from Javascript Promisify utility that transforms a callback into a promise. Installation go get github.com/d...
{object[] values =newobject[] {1,2,3}; MyEnumerator it=newMyEnumerator(values);while(it.MoveNext()) { Console.WriteLine(it.Current); } } 这个例子很简单,也很容易实现,现在假设同时有两个线程去迭代这个集合,那么使用一个MyEnumerator对象明显是不安全的,这正是IEnumerable存在的原因,它允许多个调用者...
