Next, we will see how to create and use functions . Next, we will see how to create and use functions . Next, we will see how to create and use functions . We will learn later how to define and use functions and procedures. This also means you can't conditionally define functions using function declarations:. Combinations with other parts of speech
从step1开始使用函数 ,为feed中的所有activity打分。 Use the function from step 1 to score all activities in the feed.Recursion is the definition of a function using the function itself; Using the function in expressions lets you use it in multiple ways.Before we use a function , we need to define that particular function. . Well-structured programs usually make extensive use of functions . Functional Decomposition Well-structured programs usually make extensive use of functions . 我们很快就会进入这个问题,但我们使用函数 背后的第一个原因是它们的可重用性。 We will be getting into that shortly, but the first reason behind why we use functions is because of their reusability. Hooks可以使得你始终使用函数 ,而不必在函数、类、高阶组件和reader属性之间不断切换。 Hooks let you always use functions instead of having to constantly switch between functions, classes, higher-order components, and render props. 程序员通过使用函数 减少了编码时间和调试时间,从而减少了整体开发时间。 Programmers reduce coding time and debugging time, thereby reducing overall development time, by using functions . 你可以使用函数 表达式来创建生成器,只需在function关键字和圆括号之间添加星号(*)。 You can use function expressions to create generators by just including a star(*) character between the function keyword and the opening parenthesis. 这个模式对于使用函数 作为返回值(即从父函数中返回它们)有很大的限制。 This model is a big restriction for using functions as functional values(i.e. returning them from parent functions). . 然而,在目前情况下,我们将使用函数 应用而不是字符串连接作为组成的模式。 However, in the present case we will use function application rather than string concatenation as the mode of composition. 像任何其他高级编程语言,JavaScript还支持使用函数 编写模块代码所需的所有特性。 Like any other advanced programming language, JavaScript also supports all the features necessary to write modular code using functions . 例如,您可以使用函数 计算简单的平均、加权的平均值或排除特定值的平均值。 For example, you can use function to calculate a simple average, a weighted average, or an average that excludes specific values. 通过使代码模块化,可以更容易地在其他程序中重用代码,并且使用函数 通常会使代码更具可读性。 They make it easier to reuse code in other programs by making it modular, and using functions often makes the code more readable. 在这个时候可能不理解这个例子,因为我们已经使用函数 和全局变量,这些到目前为止都未作介绍。 You may not understand this example at this time because I have used function and global variables, which I have not explained so far. 下面的示例显示使用函数 print()打印不同的数据类型:. The following example shows using function print() to print different data types:. 为此,我们可以”打开”文档使用函数 jsonb_array_elements做这样的事情:. For that we can“unwrap” documents using function jsonb_array_elements to do something like that:. 对于其他进制,我们应该使用函数 parseInt(我们将在本章后面看到)。 For other numeral systems, we should use the function parseInt(which we will see later in this chapter). 在第一章中,我们学会使用函数 作为组合和抽象的手段。 In Chapter 1, we learned to use functions as a means for combination and abstraction. You're not allowed to use the function pointer fn as a return type, for example. 您还可以使用函数 (如SUM函数)来计算工作表中的值。 You can also use a function (like the SUM function) to calculate values in your worksheet. MetaEditor可识别语言结构:如何使用函数 的建议提示,以及加亮源代码里的多种元素。 MetaEditor can recognize language structures: suggests tips on how to use functions and highlights various elements of the program source code. 稍后我们将看到如何使用函数 列表显示数据,像表1-1显示的那样。 Later we will see how to use functions when tabulating data, as in 1.1.
