Can someone explain what this code does and mean? I'm supposed to figure out what this means/does for my class assignment but, I don't understand what the -Infinity is supposed to do and I don't understand the point of the if statement. function highScore(finalpts) {
var end = -Infinity;
for (var i =0; i != finalpts. length; ++i) {
if (finalpts[i] > end) {
end = finalpts[i];
}
}
return end;
}
