Note

Bookmarklets are constrained by a single line, so they can be written in plain JavaScript with properly used semicolons, or encoded with base64.

Update:

Unfortunately, due to increasing security restrictions in modern browsers, bookmarklets using eval are becoming less reliable and may not work on all websites.
Instead, use https://minify-js.com/ or similar services to minify the code into a single line without eval.

javascript:var who = 'world'; alert('Hello ' + who); // says 'Hello world'

javascript:eval(atob('Cgl2YXIgd2hvID0gJ3dvcmxkJwoJYWxlcnQoJ0hlbGxvICcgKyB3aG8pCg==')) // says 'Hello world'

The advantage of plain format is that it can be easily edited inline or with https://beautifier.io/, but it loses all formatting.
If the script is more complex, contains comments or formatting is relevant, the code as a whole can be encoded with base64 https://www.base64decode.org/ or the included toBase64Bookmarklet function toBase64Bookmarklet(() => { /* your code here */ }).

toBase64Bookmarklet(() => {
	var who = 'world'
	alert('Hello ' + who)
})
// Result: "javascript:eval(atob('Cgl2YXIgd2hvID0gJ3dvcmxkJwoJYWxlcnQoJ0hlbGxvICcgKyB3aG8pCg=='))"
