When we're highlighting all the people that show
up in a search from the search bar, we need
to fairly expensively build a regex from the
query:
query = query.toLowerCase();
query = query.replace(/[\-\[\]{}()*+?.,\\\^$|#\s]/g, '\\$&');
const regex = new RegExp('(^' + query + ')', 'ig');
Even though the final regex is presumably cached, we
still needed to do that `query.replace` for every person.
Even for relatively small numbers of persons, this would
show up in profiles as expensive.
Now we just build the query once by using a pattern
where you call a function outside the loop to build
an inner function that's used in the loop that closes
on the `query` above. The diff probably shows this
better than I explained it here.
