In JavaScript, the function Math.max() accepts variable number of arguments and returns the biggest of them.
If you pass a couple of arrays into Math.max they will be first converted to strings and then into numbers:
console.log(Math.max([ 0 ], [ 1 ])); // 1
console.log(Math.max("0", "1")); // 1
console.log(Math.max(0, 1)); // 1
Booleans will be also converted to numbers. true becomes one and false becomes zero:
console.log(Math.max(true, false)); // 1
console.log(Math.max(0, 1)); // 1
Now the condition inside of an if statement can be simplified and we can make sure we’re getting into the else branch:
if (1 > 1) { // false
console.log('array won');
} else {
console.log('array lost');
}
ANSWER: The string array lost will be logged to the console.
