how to use the buffertime function from the rxjs library in javascript

The bufferTime function from RXJS library is used to distribute values emitted by an observable into a series of buffers over time. This is useful when you want to collect groups of time-related events and process them as a batch.

Here is the syntax for using bufferTime function:

index.tsx
observable.bufferTime(timeSpan, bufferSize, scheduler);
56 chars
2 lines

• timeSpan: The amount of time in milliseconds to create a buffer for.
• bufferSize: The maximum number of values to include in each buffer.
• scheduler (optional): The scheduler object to use for managing buffers.

Here is an example of how to use the bufferTime function with an observable that emits values every 500ms:

index.tsx
const { interval } = rxjs;
const { bufferTime } = rxjs.operators;

const source = interval(500);
const example = source.pipe(bufferTime(2000)); // buffer values every 2 seconds

example.subscribe(val => {
  console.log(`Buffered Values: ${val}`);
});
251 chars
10 lines

In this example, the observable source emits a value every 500ms. The bufferTime operator is applied to source with an argument of 2000, which creates a buffer every 2 seconds. Each buffer contains the latest values emitted during that 2 second window.

The output result of the example observable is then subscribed to and passed to the console.log statement. This will output the latest values collected in the buffer whenever a buffer is full or whenever the underlying source observable completes.

I hope this gives you an idea of how to use the bufferTime function from the RXJS library in your JavaScript projects.
