http://pauloancheta.com/ruby/wat/2018/03/23/explaining-wats/ A few weeks ago, a co-worker found something really interesting. He posted on our slack channel this line of code. Does anyone know what the output of this is? “(data)”.gsub(“(data)”, “15\01\2018”)

If you were too lazy to open your irb here’s the output: “15(data)1018”
