Why are commands in console used without semicolon?

Hi there, just a quick question that came up while I was watching the video. Dave uses different commands in the console to add and remove numbers from an array, as well as print out the array. He doesn't add a semicolon after nums.shift() etc. Why is that?

For writing code, using semicolons at the end of statements is a "best practice". But unless "strict" mode is being used, they are optional unless another statement begins on the same line.

Since console commands are temporary and generally entered one at a time, it's convenient to omit the semicolon.
