Zero, one, two, Freddy’s coming for you
This post continues the series of articles, which can well be called “horrors for developers”. This time it will also touch upon a typical pattern of typos related to the usage of numbers 0, 1, 2.

Today we are going to talk about the errors found in another project by Microsoft, PowerShell.
