The #100DaysOfCode challenge is a set of rules and an online community that help people learn to code by creating a habit of consistent daily self-study. After describing who I am, what I do and why I committed to the challenge I describe key takeaways of what I learned as a digital marketer during my first 100 days of studying programming languages like Python, PHP, JavaScript, jQuery, HTML and CSS. In the last part of the article I thank creators, contributors and community members of the #100DaysOfCode project as well as FreeCodeCamp.org, online documentations and inspiring developers. Throughout the document I provide links for anyone that is interested in learning how to code but does not know where to start.
