Question

What should max be initialized to? I’ve been trying to work it out, but have had no luck.

NUMBER_OF_INPUTS = 5;

var i;
var max;
var userInput; // Input from user

max = ???? ;
for(i=0; i<NUMBER_OF_INPUTS; i++)
{ userInput = parseInt(prompt('Enter input: '));
if (userInput > max)
max = userInput;
}

alert('Max: ' + max);

Answer 1

Use the Javascript Number.NEGATIVE_INFINITY constant. That way any user input will be bigger than what the variable is initialized to since NEGATIVE_INIFINTY is smaller than all other numbers that JS can represent.
