In the process of developing a web application, I am facing a challenge. There is an input field where users can enter a number and next to it, I want to display the double of that number as the output. While this can be easily achieved using client-side JavaScript with jQuery syntax, there are certain requirements that necessitate performing the computation server-side.
My initial approach was to handle the calculation server-side and then update the result on the client-side by calling the API. However, issues arise when dealing with asynchronous AJAX queries in response to user input changes, leading to inconsistencies in the displayed results due to potential delays in network or server processing times.
I believe this situation is common among developers. How can I effectively address this issue? Is transitioning to a front-end framework like Vue.js advisable even though the back-end computation must still occur? Do front-end frameworks offer solutions for managing these challenges? Alternatively, is there a straightforward way to tackle this problem using vanilla JavaScript? Any advice would be greatly appreciated!
