Delete worst log(n) log(n)
All average times on this table are the same as their worst times except for Insert.

What's the use of Jade or Handlebars when writing AngularJs apps
...ity.
Aside from template extension, Jade brings nothing worthwhile to the table that Angular doesn't already supply. Let's be honest: Using the sound principle of "favour composition over inheritance" (i.e. partials), you shouldn't ever need template extensibility. Jade is hardly "easier to parse" ...
