Dive into secure and efficient coding practices with our curated list of the top 10 examples showcasing 'normals' in functional components in JavaScript. Our advanced machine learning engine meticulously scans each line of code, cross-referencing millions of open source libraries to ensure your implementation is not just functional, but also robust and secure. Elevate your React applications to new heights by mastering the art of handling side effects, API calls, and asynchronous operations with confidence and precision.
// Update options:
// 1) direct update buffer
// bunnyPositionBuffer.bufferData(positionData)
//
// 2) direct update via ctx
// ctx.update(bunnyPositionBuffer, { data: positionData })
//
// 3) update command
// const updateCommand = ctx.update({ target: bunnyPositionBuffer, data: positionData })
// ctx.submit(updatePositions)
// FIXME: pre-allocate buffer
// FIXME: add update command
// What are the update patterns in other APIs?
