Delete deno folder
Firstly, You can delete the .deno folder in your distro. Then, you can delete it with sudo rm -R $HOME/.deno command.

In the second step, You can delete the deno configuration in .bashrc file. Which is added automatically on the installation time.
open bash .bashrc file with any IDE. for example, I use nano Linux IDE and open .bashrc file with nano nano ./.bashrc
After oping .bashrc file, then you find the following configuration.
# Manually add the directory to your $HOME/.bashrc (or similar)
export DENO_INSTALL="/home/rajdeepsingh/.deno"
export PATH="$DENO_INSTALL/bin:$PATH"
