i using book called angularjs , running. gives example of using exceptget . example: mockbackend = $httpbackend; mockbackend.exceptget('/api/note') .respond([{id:1, label: 'mock'}]); my question is, isn't point of unittesting server calls make server call , verify server call expect be? with above code, not make server call , force response equal [{id:1, label: 'mock'}] ? what's point of doing if aren't able check actual response is? because later on in code, checks response so: mockbackend.flush(); expect(ctrl.items).toequal([{id:1, label: 'mock'}]); wouldn't equal [{id:1, label: 'mock'}] because that's forced response equal? what's benefit of having .respond() , controlling response? if hit api endpoint on server in unit test, it not unit test anymore - involve more component under test (controller/service/provider etc) - network, web server, backend itself, database etc - becomes integrat...

i reimplementing memoize function using arguments object. wondering why work. example, passing in 2 arguments: var args = array.prototype.slice.call(arguments); // input: 1,2 then store args array object. example, var obj = {}; obj[args] = 2; if call object, see as: { 1,2: 2 }/*shows this*/ { [1,2]: 2 }/*but not this*/ not wanted second object, curious happening under hood. call javascript coercion? object property names strings. when do: obj[args] = 2; it treats as obj[args.tostring()] = 2; and tostring() method of arrays equivalent .join(",") , above equivalent to: obj[args.join(",")] = 2; which matches result saw.

(the direction of n perpendicular a-b plane). way calculate n = ax*by - ay*bx . base::crossprod not calculation, , in fact produces vector dot-product of 2 inputs sum(ax*bx, ay*by) . so, can write own vectorxprod(a,b) function, can't figure out crossprod doing in general. see r - compute cross product of vectors (physics) according function in r: crossprod (x,y) = t(x)%*% y faster implementation expression itself. function of 2 matrices, , if have 2 vectors corresponds dot product.
