John Larsen is a programmer and author of helpful books for programmers. He started programming on a Vic20, tried to be creative with DOS, taught C#, flirted with PHP and now is happiest indulging in full-stack JavaScript.

A maths teacher for 25 years, John developed apps for teaching, learning, planning and admin and is still involved in research relating to ICT in education.

John has also taught English in Japan and is improving his Japanese bit by bit. He visited Japan for the Rugby World Cup and looks forward to going back when we're all a little less contagious.
