Restored this on the grounds that it matches all three of the stated requirements: |
|||
- They should be distinct from (nested) for loops within the syntax of the language. |
|||
- They should return either a list or an iterator (something that returns successive members of a collection, in order). |
|||
- The syntax has parts corresponding to that of set-builder notation. |
|||
It uses no for loops, |
|||
returns a list, |
|||
and has the parts corresponding to set-building notation. |
|||
The previous alternative is useful, but is restricted to a smaller subset of JavaScript, and arguably uses for loops. |
|||
If we are to delete one, we should delete both, but I am not sure that either approach has much value. |
|||
Both examples are illustrative of such resources as JavaScript is currently able to provide for patterns of this kind. |

: Hi Hout, unfortunately map & filter are the other way of doing things that are not list comprehensions. map&filter are arguably as well known a method as list comprehensions and some languages have both map & filter and list comprehensions as part of the language. The [[wp:List comprehension]] article also makes the distinction up front. Maybe I should add that fact to the task? --[[User:Paddy3118|Paddy3118]] ([[User talk:Paddy3118|talk]]) 20:16, 7 September 2015 (UTC) |
