Simple task, I am just trying to have the data that correlates to a menu item hidden until it is clicked. However, I feel like this can be optimized. There is 2 ng-repeats but I can't think of another way to do it. How'd I do?
See JSFiddle:
<script>
var app = angular.module('app', []);

The simplest type of data structure is a linear array. This is also called one-dimensional array. In computer science, an array data structure or simply an array is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key. An array is stored so that the position of each element can be computed from its index tuple by a mathematical formula.
For example, an array of 10 integer variables, with indices 0 through 9, may be stored as 10 words at memory addresses 2000, 2004, 2008, … 2036, so that the element with index...

Recently the java-8 tag was created to apply to Java8 specific questions.
There is no doubt that the questions are, in fact, Java8 questions. The meta question though, is:
Should java-8 exist, and if it should, what should it be, a full tag, or a synonym to java?

So I am defining a variable as false unless a condition is found:
some_variable = false
if some_condition
some_variable = true
end
if some_variable == false
puts "Some variable is #{ some_variable }"
end
However, is defined more idiomatic?
if some_condition
some_variable = true
end

public int makeSmaller(int num) {
int result = Math.abs(num) - 1;
if(num > 0) return result;
else return -result;
}
Why not just this?
public int makeSmaller(int num) {
return num - (num/Math.abs(num));
}
The parenthetical part will always have the same sign as the number, and will...
