Hi there!

We're back. I had a great week at Node Summit and learned about some new things coming out in the JavaScript world (optional chaining was my favorite) and spoke about Electron (and jokes, obviously)!

Something that interested me this week

This past weekend was the Seattle Mechanical Keyboard meetup! It was a great time. I spoke about designing XDA Scrabble, watched a SUPER interesting talk about stenography with keyboards, and saw so many keyboards.
So.
Many.
Keyboards.
It was a blast, and I can't wait for next time!

Interview question of the week

We had a solid showing of responses this week for removing leading zeros! Boom bang boing bloop. Click those words to get the scoop.

Also, Andrew emailed this one-liner in:
const removeLeading = (arr) => arr.reduce((acc, curr) => (!acc.length && !curr ? [] : [...acc, curr])); 

This week's question:
Write a function that merges n sorted arrays.

Example:
arr[][] = [ [1, 3], [2, 4, 5], [0, 9, 10, 11] ];
> mergeN(arr)
> 0 1 2 3 4 5 9 10 11
