Happy International World Standards Day! We may not have set ISO standards for development, but we do have 'Best Practices', even if not everyone agrees about what they are, all of the time. This week, Juan Cruz Martinez says all projects should follow best practices to increase efficiency and quality in "Best Practices Every Node Developer Should Follow" while Eren Yatkin takes us through the "Proper Way To Connect MongoDb — NodeJs."
For more custom creations, Milton Marma gives a step step in "Create Custom Pipe in Angular to Replace Null Value With a Text" and Digamber Singh shows us how to "Create Custom Markdown Pipe in Angular 10 to Parse HTML". For those looking ahead in time, check out Fernando Doglio's "What’s In The Future For JavaScript?" on Bits and Pieces.

We, however, use a keyed trie for our main document store. Thus no structural changes occur as in B-trees. Furthermore, we developed a new sliding snapshot algorithm to version the data pages and store variable-sized page fragments.
