   * Converts an infix expression to a postfix expression.

   * This method is used to transform infix expressions, which are more human-readable,

   * evaluated more efficiently by a computer. The conversion is based on the operator
   * priority defined in _OperatorPriority.
   *
   * The function employs a stack-based algorithm for the conversion and caches the result
   * to improve performance. The cache keeps track of each converted expression's access time
   * to manage the cache size and optimize memory usage. When the cache size exceeds a specified
   * limit, the least recently accessed items in the cache are deleted.
   *
   * The cache mechanism is particularly helpful for shader compilation, where the same infix
   * expressions might be encountered repeatedly, hence the caching can speed up the process.
   *

because integer math is slow on GPUs,but should be set to an integer>=1
param jitterFraction Number between 0 and 1 for how far to bump the ray in stride units
to conceal banding artifacts,plus the stride ray offset.
param maxSteps Maximum number of iterations. Higher gives better images but may be slow
param maxRayTraceDistance Maximum camera-space distance to trace before returning a miss
param selfCollisionNumSkip Number of steps to skip at start when raytracing to avoid self collisions.

It looks like you wrote useEffect(async () => ...) or returned a Promise. Instead, write the async function inside your effect and call it immediately:

useEffect(() => {
  async function fetchData() {
    // You can await here
    const response = await MyAPI.getData(someId);
    // ...
  }
  fetchData();
}, [someId]); // Or [] if effect doesn't need props or state
