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;
}

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
