Make executables with shebang

You can make a JavaScript or TypeScript file executable in the shell, with the shebang #!

With this JS file at ~/bin/sayHi.js:

#!node
console.log('Hi there!');

You can execute it with:

chmod 744 ~/bin/sayHi.js
# instead of typing `node ~/bin/sayHi.js`
# you can just
~/bin/sayHi.js

And you can do similar things for TS files ~/bin/sayHi.ts:

#!bun run
console.log('Hi there from bun run!');

Or shell script ~/bin/sayHi.sh:

#!zsh
echo "Hi there from zsh!"
