Given:

console.log(boo); this outputs undefined

Given:

var boo = 1;

console.log(boo); this outputs 1

After defining boo and setting to 1, how can I then reset boo, so that console.log outputs undefined?

Thanks

delete boo

Don't use var boo = undefined. undefined is just a variable and if someone sets undefined = hello then you'll be getting hello everywhere :)

EDIT:

null wasn't same as undefined. removed that bit.
