海外TECH	DEV Community	How to use loops in dart programming language.	https://dev.to/rashtech/how-to-use-loops-in-dart-programming-language-407g	How to use loops in dart programming language Understanding the types of loops in Dart and how to use them PrerequisitesTo test this code you should be able to access Dartpad dev or have a Dart SDK platform where you can run this code What are loops The loop is a function of code that allows you to run a desired request repeatedly until an outcome is achieved Loops work by checking the given condition and repeating the process until that condition is met Types of loops in dart For loop While loop Do while loop A type of while loop For in loop A type of for loop For each loop A type of for loop For loop In the main function we created the for loop by using the for keyword We then proceeded by creating an integer variable named I and assigned to it The condition here states that i lt i for i is less than adding This means as long as I is less than add Here is the output While loop In this type of loop it is written with the keyword while before the condition On every iteration the loop checks the condition While condition Here is the output Note Avoid writing a condition that is always true to avoid falling into an infinite loop Do while loop Just as the name indicates it s simply do while It carries the function first before checking the condition The condition is placed last in this type of loop It is executed at least once Here is the result For in loop For in loop is used to loop through the properties of an object This loops through the properties in order For everything in this variable Here is the output For each loop In this type of loop you can simplify the for in loop The for each loop applies to collections For Example Here is the output	2023-07-17 17:47:20
海外TECH	DEV Community	How to use mergeMap and forkJoin to handle multiple API requests in Angular 🚀	https://dev.to/mana95/how-to-use-mergemap-and-forkjoin-to-handle-multiple-api-requests-in-angular-412p	How to use mergeMap and forkJoin to handle multiple API requests in Angular Hey Forks In this Article I will explore the process of how to handle multiple API requests in Angular Handling multiple API requests in Angular is a common scenario in modern web development It s essential to implement an efficient and maintainable solution to avoid issues such as nested subscriptions In this article we will explore the proper way to handle multiple API requests using the mergeMap and forkJoin operators from the Angular RxJS library First of all I will explain the problem problem because we are not using nested subscriptionsIn the real world it is common to make multiple API calls in our web applications When navigating to a page it is often necessary to retrieve data from various APIs In Angular the subscribe operator is typically used to fetch data from a single API call However when dealing with multiple API calls there are more effective methods to implement this We can initially solve the problem using the subscribe operator and then improve upon it by utilizing mergeMap and forkJoin Subscribe Normally this technique is quite simple However when we trigger a new subscription for each and every value emitted by the Observable of call it can result in the creation of numerous unhandled Observables and Subscriptions All of these entities remain in memory for the time being leading to potential issues Here is nested subscription exampleexport class DevToComponent implements OnInit todoValue string comment any constructor private http HttpClient ngOnInit void this retrieveDefaultData retrieveDefaultData void this http get pipe map todo gt todo subscribe todo gt this todoValue todo this http get this todoValue comments subscribe coment gt this comment coment It s important to note that when you subscribe to an Observable multiple times your subscribers won t listen to the exact same source Instead each subscription triggers a new copy of the defined Observable pipeline MergeMap This operator takes an input observable applies a transformation function to each emitted value and merges the resulting observables into a single output observable By using MergeMap we can avoid nested subscriptions and achieve a more streamlined and efficient approach to handling asynchronous requests We can use the MergeMap when we need data information from first API request to second API request export class DevToComponent implements OnInit todoValue string comment any mergeMapResult any constructor private http HttpClient ngOnInit void this retrieveDefaultData retrieveDefaultData void this http get pipe map todo gt return todo mergeMap todo gt this http get todo comments subscribe response gt this mergeMapResult response Using mergeMap avoids nested subscriptions you can avoid nested subscriptions and flatten the asynchronous operations This leads to cleaner and more readable code as the operations are executed sequentially instead of nesting multiple subscription callbacks ForkJoin This operator when you have multiple parallel API requests that are independent of each other and you want to wait for all of them to complete before taking further action you can use the forkJoin operator instead of nested subscriptions We can use the ForkJoin calling independent multiple API requests export class DevToComponent implements OnInit todoValue string comment any firstApiResult any secondApiResult any constructor private http HttpClient ngOnInit void this retrieveDefaultData retrieveDefaultData void const firstAPI this http get const secondAPI this http get forkJoin firstAPI secondAPI we can use more that api request subscribe result gt this will return list of array of the result this firstApiResult result this secondApiResult result Using forkJoin simplifies the handling of parallel API requests by providing a clean and efficient way to wait for all requests to complete It eliminates the need for nested subscriptions improving code readability and maintainability Note Note that if any of the source observables in forkJoin errors before completing the entire observable will error and no result will be emitted So it s important to handle error cases appropriately when using forkJoin ConclusionBy adopting the use of mergeMap and forkJoin in RxJS you have acquired a powerful technique for handling multiple API requests without resorting to nested subscriptions This approach not only improves the readability and maintainability of your code but also allows for efficient parallel execution of asynchronous operations Thanks for reading the whole story	2023-07-17 17:00:47
