How to make API calls inside for loop?
Let’s modify the processUsers function to make the API calls parallel. As seen in the above code, you pushed each of the promises without awaiting it into an array. This makes all the API calls to start at the same time. The time taken for the whole process to finish will be the time taken by the longest promise to finish execution.
What kind of loop is list.generate ( )?
This means that List.Generate () is a sort of header-controlled loop. In contrast to foot-operated loops, this loop is characterized by the fact that its execution condition is checked before the first loop pass.
When to use list generate in excelando loops?
In another post on “Excelando” loops with List.Generate are used to optimize the call of a Web API. When retrieving the API, individual pages must be addressed, whereby it is not known in advance how many pages there are to be read.
How to generate a list using list generate?
“List.Generate () generates a list of values based on up to four parameters.” So List.Generate () expects up to four parameters to be handed over to generate a list. All these parameters are in turn functions.
How do you make API calls in JavaScript?
You have used async/await to make API calls. You await each promise call to complete so that you can append the result to the corresponding JSON object. The above works fine and gives you the expected result. But there is an issue with the above code.
How to loop through data from a data file?
What if you want to loop through data from a data file? This would allow you to test for hundreds of scenarios. In the Postman app, you can import a CSV or JSON file, and use the values from the data file in your requests and scripts. You can do this using data variables with a similar syntax as we do when using environment and global variables.
How to loop through a JSON response in JavaScript?
In this quick tip, I’ll demonstrate how you can use JavaScript to parse the server’s response, so as to access the data you require. This process will typically consist of two steps: decoding the data to a native structure (such as an array or an object), then using one of JavaScript’s in-built methods to loop through that data structure.
How to make API calls for each value in an array?
JavaScript: How to make API calls for each value in an array and get an array of results. Today I had to call an API with for a bunch of ids and get the results for each of those ids. Now the problem is, I need to collect the results from all of those API calls. And I did not want to use plain old for loop for this today.

We have the regular ‘for’ loop, ‘for/in’, ‘for/of’ and the regular ‘while’ loop. Each have their strengths, weaknesses and use cases. By using an example of looping over multiple pages of an API I want to take a look at another type of loop, the ‘do… while’ loop.
How to use a DO…WHILE loop for API pagination-Dev?
We want to use similar logic for our API pagination. The key of the do… while loop is in the while condition. This code block controls how often a loop will run. Make sure you don’t create infinite loops because that can crash your browser or node environment. These loops are the ones that never finish.
