The problem Drawing board solves

The drawing board can be used on any browser without the need of installing applications like MS Paint. The user can use brushes having different colors and sizes. There is an option to redo, undo or erase the entire drawing. The user can save their drawing in the form of a screenshot after completing it.

Challenges I ran into

Initially, it was a bit difficult working with HTML Canvas as it was very challenging to add the elements and make changes. But after referring to the HTML canvas documentation on w3schools and MDN web docs along with drawingboard.js documentation I was able to make the website.
