Hi Sir, Can You answer this question?? Write a vanilla javascript program that returns 0 when input is 1 and 1 when input is 0. Do not use if, for, while, switch, do statements. Write as many implementation as you can think of (minimum 4 ways).
Hello. Well, I think this is it:
f1 = (input) => { return (1+input)%2 };
f1(0); // 1 f1(1); // 0
f2 = (input) => { return (1-input)%2 };
f2(0); // 1 f2(1); // 0
f3 = (input) => { return ~input&1 };
f3(0); // 1 f3(1); // 0
f4 = (input) => { return +!input };
f4(0); // 1 f4(1); // 0
I'm waiting for your comments about it. Thank you.
return [1, 0][input]
