| holmdunc | and the confusing thing on the JS side is that it has Maps too: developer.mozilla.org/en-US/docs/W...bjects/Map | 09:48 | |
| lizmat | that'd be raku.land/zef:lizmat/Hash::Ordered in Raku | 09:54 | |

| Nemokosch | well, Map is more of a "modernism" in JS | 10:15 | |
| holmdunc | Objects were Good Enough for the first 20 years! | 10:29 | |
| lizmat | feels more like a PHPism in JS to me | 10:31 | |
| if I remember correctly, hashes in PHP were just arrays of pairs with an associative interface on them | |||
| aka, the order of insertion was kept | |||
| but with severe performance issues for large hashes, especially if the key didn't exist | 10:32 | ||
| Nemokosch | I think in JS they just genuinely recognized that objects, or even records, have different implication and different "baggage" compared to an associative data type | 10:41 | |
| now if you do Typescript, you can still use objects the associative way but it's kinda cumbersome and the old restrictions also hold so like there is no real reason to use them that way | 10:42 | ||
| the Mozilla site does mention the insertion order, honestly I didn't even know about it, and after checking the site, it still appears to me that it's not "the killer feature" of Map, just a kind of cherry on top thing | 10:45 | ||
| anyway, I have a Raku question! 😄 | 10:46 | ||
| what's the idiomatic way to create an infinite sequence from an iterable that loops through the elements, much like itertools.cycle in Python? | |||
| lizmat | |(iterable) xx * | 10:59 | |
| m: my @a = 1,2,3; say (|@a xx *)[^10] | 11:00 | ||
| camelia | (1 2 3 1 2 3 1 2 3 1) | ||
| lizmat | Nemokosch ^^ | ||
| Nemokosch | yes well, this is what I was thinking of | 11:27 | |
| thanks anyway | |||

| librasteve | role Object::Literal { has %.object; method new( %object ) { return self.bless( :%object ) } method FALLBACK( $key ) { %!object{$key} ~~ Callable ?? %!object{$key}() !! %!object{$key} } } my Object::Literal $olly .= new( %( :a(7), :b(42), :c({ "hi {$olly.b}" }) ) ); say $olly.c; #hi 42 | 14:15 | |
| ^^^ thought it would be interesting to try some way to do method call semantics on a Hash | 14:16 | ||
| since this is the example set out at medium.com/the-codehub/object-lite...affed2d6b4 | |||

tea3po left,

|
|||
| only snag is I can't work out how to get the Callable to be a method on the object like :c({ "hi {self.b}" }), | 14:18 | ||
| but since it is a literal it seems fair to use the var name itself | 14:19 | ||
