why infinity property used command (rather result) for example, code below works, result isn't expected. alert(isodd(infinity)); function isodd(num) { return num%2==1; } infinity property of global object holds numeric value representing mathematical concept of infinity . don't know normal definition called "command." with regard edit, should return false (i ran confirm suspicion, , did on browser). correct, infinity not considered odd number.

can explain difference between dictionaries , hashtables? in java, i've read dictionaries superset of hashtables, thought other way around. other languages seem treat 2 same. when should 1 used on other, , what's difference? the oxford dictionary of computing defines dictionary as... any data structure representing set of elements can support insertion , deletion of elements test membership. as such, dictionaries abstract idea can reasonably efficiently implemented e.g. binary trees or hash tables, tries, or direct array indexing if keys numeric , not sparse. said, python uses closed-hashing hash table dict implementation, , c# seems use kind of hash table (hence need separate sorteddictionary type). a hash table more specific , concrete data structures: there several implementations options ( closed vs. open hashing being perhaps fundamental), they're characterised o(1) amortised insertion, lookup , deletion, , there's no excuse begin-...
