jQuery performance issues with large datasets in dynamic table rendering
I'm optimizing some code but After trying multiple solutions online, I still can't figure this out. I'm prototyping a solution and I need help solving Currently developing a dashboard that displays real-time data in a table format. The table can potentially have thousands of rows, depending on user selection. While integrating jQuery for DOM manipulation and event handling, I've noticed significant performance drops when rendering the table with the `.append()` method for each row. Here’s the code I’m using to populate the table: ```javascript let rows = ''; data.forEach(item => { rows += `<tr><td>${item.id}</td><td>${item.name}</td><td>${item.value}</td></tr>`; }); $('#myTable tbody').append(rows); ``` This approach works, but it becomes unresponsive with larger datasets. I’ve tried optimizing it by using `DocumentFragment` to batch DOM updates when rendering, as follows: ```javascript let fragment = document.createDocumentFragment(); data.forEach(item => { let row = document.createElement('tr'); row.innerHTML = `<td>${item.id}</td><td>${item.name}</td><td>${item.value}</td>`; fragment.appendChild(row); }); $('#myTable tbody').append(fragment); ``` While this is slightly better, the performance still lags after about 500 rows. I’m also concerned about jQuery’s `.fadeIn()` and `.fadeOut()` animations that I want to apply to rows based on user interactions, but they add further lag. Could anyone suggest best practices for handling large datasets with jQuery, especially in terms of rendering efficiency? Are there alternatives to jQuery that would handle this better? Any insights or examples would be greatly appreciated! I'd really appreciate any guidance on this. Any pointers in the right direction? My team is using Javascript for this mobile app. Could this be a known issue? I'm using Javascript 3.9 in this project.
