Shorthand for calling functions conditionally

You actually can create a shorthand for calling functions conditionally, and I just found out this yesterday 😭

const type = 'greeting';

function greeting() {
    console.log('hello')
}

function goodbye() {
    console.log('goodbye')
}

if(type === 'greeting'){
    greeting()
}else{
    goodbye()
}

Instead of doing that, we can reduce our line number this way

(type==='greeting' ? greeting:goodbye)()
