Published the final part of Cross-site scripting attack for the series 'What a frontend developer should know about web security' covering about DOM based XSS attack, General Best practices for preventing XSS, Testing tips for XSS and the various references that helped me to put it all together. In the next part of the series I plan to write about Cross-site Forgery attacks. 
I realised that the best way of learning is by sharing and teaching to others, and blogging is a great way to self learn and also share your learnings.  https://dev.to/ms_74/cross-site-scripting-xss-attack-part-3-2fkc
