if remove 1 element array using splice() so: arr.splice(i, 1); will o(n) in worst case because shifts elements after i? or constant time, linked list magic underneath? worst case should o(n) (copying n-1 elements new array). a linked list o(1) single deletion. for interested i've made lazily-crafted benchmark . ( please don't run on windows xp/vista ). as can see though, looks constant (i.e. o(1) ), knows they're doing behind scenes make crazy-fast. note regardless, actual splice fast. rerunning extended benchmark directly in v8 shell suggest o(n) . note though need huge array sizes runtime that's affect code. should expected if @ v8 code uses memmove create new array.

let's have array of objects $objects. let's these objects have "name" property. this want $results = @() $objects | %{ $results += $_.name } this works, can done in better way? if like: $results = objects | select name $results array of objects having name property. want $results contain array of names. is there better way? i think might able use expandproperty parameter of select-object . for example, list of current directory , have name property displayed, 1 following: ls | select -property name this still returning directoryinfo or fileinfo objects. can inspect type coming through pipeline piping get-member (alias gm ). ls | select -property name | gm so, expand object of type of property you're looking at, can following: ls | select -expandproperty name in case, can following have variable array of strings, strings name property: $objects = ls | select -expandproperty name
