I am curious kid on the web, trying to learn more about life and other things. I enjoy building things and my medium of expression is mostly code. I have been dabbling with OpenEdx recently. I love to talk about distributed system, I have taken up learning Rust recently and been writing Python, Golang and JavaScript for a while.

Hello people!! what’s up! So I am back with another blog and this time is home made pure JavaScript. I have been introduced to JavaScript during FSMK summer camp and I have been flabbergast ever since with the potential this scripting language has. So JavaScript was taught to us by Gautham Pi sir who is a proud founder of Jnaapti , he was generous enough to offer free online course on JavaScript to whoever was interested. I was curious, so I enrolled and to be honest it helped me lot I had amazing experience brainstorming on problems and learning entirely new concepts. Shree Laxmi ma’m made sure that we are regular and disciplined about the course. The entire concept was amazing and I really I loved the way it worked out for me . THANK YOU [JNAAPTI](//jnaapti.org) .Now, coming back to the JavaScript , I came up with the following approach during the camp. The problem was while using an outdated tag called I wanted that my scrolling text should stop when user has its mouse over the text and at the same time it should highlight the content. So, as someone told me that first you should know the problem , then think about how to solve it and if solving requires learning a new skill then learn it . Yeah, So what I did was , you guessed it right I used . . . “JavaScript” TADA!!
The approach was to make the scrolling stop and highlight the text a.k.a “reduce the opacity” when user points on the text and resume the same when user takes out the mouse. I wrote a small yet clever JS function for that, what my JS did was it sets the attribute called onmouseove to an inbuilt function called this.stop() and onmouseout to this.start() that reduces my job , hush!. Now , I made two functions one to increase the opacity and the other to set it back. It sounds simple right? Well it is, the the problem was the number of time i need to call those function and it WAS MAKING MY SWEET, SIMPLE, SEXY, AND GORGEOUS JS (no! I am not describing my dream girl) to look tedious so I had to do something so I made a parameterized function and incorporated into it. So, the code is ……*DRUM ROLLS *

Cool! isn’t it ! Well I think so these many lines of code did that amazing job. Ok! Something I wanted to share, to all the noobs like me who must be thinking WTH! I wrote document.getElementById when I had the option of making it a variable. The answer to that question is IT CAUSES GLOBAL VARIABLE POLLUTION, in short it increases the size of the webpage and make it heavy and difficult to load . So , try this out people hope you like it I am putting up the code for this page as well as the whole website on git to check out here . Feel free to commit and criticize ! peace out until next time.
