Food for Thought
A mindset, an example, and an action item to start the week

"Success usually comes to those who are too busy to be looking for it."

Henry David Thoreau

Mindset: Unwavering commitment to the process, not the outcome, fuels success - focus on execution, not validation.

Example: Apple's relentless pursuit of innovation, even during periods of doubt, exemplifies this mindset.

Action item: Identify one process you can refine today, and immerse yourself in its optimization.

The Quick Byte
One coding tip because you’re technical after all

This week’s coding challenge:

This week’s tip:

Async iterators in Node.js are part of the ES2018 specification and allow handling streams of data asynchronously using a for-await-of loop. This method is particularly effective for efficiently processing large or complex streams of data.


  • Handling Stream Data: Ideal for applications dealing with continuous data streams, such as logs, network traffic, or large files.

  • Real-Time Data Processing: Useful in scenarios where data needs to be processed in real-time as it becomes available.

  • Back-Pressure Management: Effective in managing back-pressure in stream processing, ensuring that data isn't consumed faster than it can be processed.


  • Non-Blocking I/O: Ensures that the application remains responsive by not blocking the event loop while waiting for data.

  • Efficient Data Handling: Enables more efficient data handling and processing, optimizing resource usage.

  • Improved Scalability: Supports better scalability of applications that need to handle high volumes of data or traffic.
