Condition assignment with and without variable bindings and logic

coinflip.js

// conditionally assign variable binding
let coinflip1;

if( Math.random() > 0.5 ) {
  coinflip1 = 'heads';
} else {
  coinflip1 = 'tails';
}


// conditionally assign constant binding
const coinflip2 = Math.random() > 0.5 ? 'heads' : 'tails';


//  awkward, but possible to perform logic in the branches via IIFE
const cointflip3 = Math.random() > 0.5 ?
  'heads' :
  (() => {
    console.log('Ouch!');
    return 'tails';
  })()
;
