海外TECH	DEV Community	[How to] write abstract functions in JS	https://dev.to/devneagu/how-to-write-abstract-functional-functions-in-js-1db	How to write abstract functions in JSAbstract functions can also be useful when you want to write code that is more modular and easy to maintain By separating the abstract concept or behavior of a function from the specific details of its implementation you can make the code easier to understand and maintain and you can avoid duplication and repetition It is generally a good idea to embrace abstract functions when you want to write code that is flexible and reusable For example if you are writing a library or framework that needs to be applicable to different contexts or situations or if you are writing a function that needs to be able to handle different types of inputs or arguments an abstract function can be a good choice Code Example To write abstract functional functions in JavaScript you can use the function keyword to define a function and use the this keyword to refer to the current object or context within the function You can also use the apply method to apply the function to different objects or contexts and the call method to call the function with specific arguments Here is an example of how you can write an abstract functional function in JavaScript function myFunction Use the this keyword to refer to the current object or context console log this property Apply the function to different objects or contextsmyFunction apply property value Outputs value myFunction apply property value Outputs value Call the function with specific argumentsmyFunction call property value Outputs value myFunction call property value Outputs value In this example the myFunction function is defined using the function keyword and it uses the this keyword to refer to the current object or context within the function The apply and call methods are then used to apply the function to different objects or contexts and to call the function with specific arguments By using the function keyword the this keyword the apply method and the call method you can write abstract functional functions in JavaScript that can be applied to different objects or contexts and that can be called with specific arguments Code Example function add x y Use the this keyword to refer to the current object or context return this value x y Apply the function to different objects or contextsconsole log add apply value Outputs console log add apply value Outputs Call the function with specific argumentsconsole log add call value Outputs console log add call value Outputs In this example the add function is defined using the function keyword and it uses the this keyword to refer to the current object or context within the function The add function takes two arguments x and y and it returns the sum of the value property of the current object x and y Code Example Define an abstract function that takes a callback as an argumentfunction myFunction callback Use the this keyword to refer to the current object or context const data this getData Get some data from the current object or context const result callback data Call the callback with the data as an argument return result Return the result of the callback Define a specific function that processes the data and returns a resultfunction myCallback data Process the data and return a result return data map item gt item value Apply the abstract function to different objects or contexts and call the specific function with the dataconst result myFunction apply getData gt value value myCallback Outputs const result myFunction apply getData gt value value myCallback Outputs Call the abstract function with specific arguments and the specific functionconst result myFunction call getData gt value value myCallback Outputs const result myFunction call getData gt value value myCallback Outputs The myFunction function then calls the callback function with the data as an argument and returns the result of the callback This means that the myFunction function is an abstract function that can be applied to different objects or contexts and that can be called with different callback functions to process the data in different ways The myCallback function is then defined as a specific function that processes the data and returns a result The myCallback function takes the data as an argument and it processes the data by multiplying the value property of each item by The myFunction and myCallback functions are then used together to apply the myFunction function to different objects or contexts and to call the myFunction function with specific arguments and the myCallback function In each case the myFunction function gets the data from the current object or context and it calls the myCallback function with the data as an argument The myCallback function then processes the data and returns the result which is returned by the myFunction function When not to right abstract functionsFor example if you are writing code that is specific to a particular situation or context and you don t need to reuse the code in different contexts an abstract function may be more complex and difficult to understand than a more concrete and specific function	2022-12-10 09:24:48
