Should I stick with MySQL [closed]

I have a web application where I'm storing data. Now I'm storing this as a javascript file and I'm hardcoding everything since all the data I need is shown to the public so I have no issues with security. It is formatted the way I want. Now I tried MySQL and it is good but for hundreds and hundreds of rows and columns with relatively large data (like small paragraphs), should I stick with MySQL as I find that to be more of a challenge to implement. Yes, it can be faster but could I just disable cache for my js file and use it like that since I find it would be much simpler and more comfortable for me.

P.S. The data is one big array with multiple objects
