About Me

I obsess over performance, efficiency and team collaboration. Human Interfaces are best built when teams are able to work interchangeably and empower one another.

Automated processes and tooling should serve development teams as well as the product, and I enjoy developing them.

I cultivate a culture of continuous learning and mentorship.

pass 1/5 · baseline

Rendering a table to an HTML string, measured in your browser. Every pass produces byte-identical output.
Stage Time
parse
sort
format
serialize
total

This benchmark runs in your browser and needs JavaScript.

  1. baseline — naive first pass
  2. precompute the key — normalise each name once, not twice per comparison
  3. one pass, no RegExp — scan for the five entities instead of building five regexes per row
  4. scan, don't split — walk the source with indexOf instead of a regex and two intermediate arrays
  5. arithmetic, not objects — group digits in a loop and derive the date without allocating a Date
