Bonus advantage to this style of programming: easy to test. Building an automated test of the functions using values similar to those below and you would always know where the inevitable bug isn't.

• Is -5 nonzero: {{playCtrl.nonzero(-5)}}
• Is 0 nonzero: {{playCtrl.nonzero(0)}}
• Is 5 nonzero: {{playCtrl.nonzero(5)}}
• Is x less than -20, or greater than 5 and less than 10?
  • -40: {{playCtrl.inSomeRange(-40)}}
  • -6: {{playCtrl.inSomeRange(-6)}}
  • 7: {{playCtrl.inSomeRange(7)}}
  • 11: {{playCtrl.inSomeRange(11)}}
• Default Data: {{playCtrl.data}}
• Filtered Data: {{playCtrl.data | filter:playCtrl.rangeFilter}}
• Test when() with truth: {{playCtrl.whenTruth}}
• Test when() with false: {{playCtrl.whenFalse}}
• Test unless() with truth: {{playCtrl.unlessTruth}}
• Test unless() with false: {{playCtrl.unlessFalse}}
• Test branch() with truth: {{playCtrl.branchTruth}}
• Test branch() with false: {{playCtrl.branchFalse}}
