1 // we have an array of objects, we want to remove one object using only the id property
2var apps = [{id:34,name:'My App',another:'thing'},{id:37,name:'My New App',another:'things'}];
3 
4// get index of object with id:37
5var removeIndex = apps.map(function(item) { return item.id; }).indexOf(37);

1//1
2someArray.shift(); // first element removed
3//2
4someArray = someArray.slice(1); // first element removed
5//3
6someArray.splice(0, 1); // first element removed

8someArray.pop(); // last element removed
9//5
10someArray = someArray.slice(0, a.length - 1); // last element removed
11//6
12someArray.length = someArray.length - 1; // last element removed

2

1someArray.splice(x, 1);
