Thereverse() method of Array instances reverses an array in place and returns the reference to the same array, the first array element now becoming the last, and the last array element becoming the first. In other words, elements order in the array will be turned towards the direction opposite to that previously stated.

The reverse() method is generic. It only expects the this value to have a length property and integer-keyed properties. Although strings are also array-like, this method is not suitable to be applied on them, as strings are immutable.


The reverse() method reads the length property of this. It then visits each property having an integer key between 0 and length / 2, and swaps the two corresponding indices on both ends, deleting any destination property for which the source property did not exist.


I believe it should be possible to reverse the ordering of blog posts, as I've seen a few other posts in the forum about it, and a solution I've tried involves creating some Custom CSS and Footer code injection, but sadly it isn't working for me.


Could someone take a look at my blog site and let me know if this would be an easy task? -100 is the blog I'm talking about.



The oldest post is from March 25 and the newest is April 7. I want the March 25 post to be appearing at the top of the page and the newer posts would be below that, with the newest all the way at the bottom of the page. (I'm hoping this also will have the affect of the "previous/next" links at the bottom of each post having the right-most link go to a newer post.)



I appreciate any help.


What's interesting is that I see a bunch of masonry references in the frame source that SquareSpace is rendering, which made me think the solution for "Masonry" blogs would work. My format is "side-by-side" though.


First thing to know is that a CSS solution (or a client-side JS solution for that matter) can only affect elements that have already been loaded up. that means that you can only reverse the order of the first n posts which squarespace. (n is set in the blog page settings and can go up to a max of 20).


remember though, if your page is set to show n articles and you add n+1 articles to your blog then you won't get the oldest post. you'll get the oldest post of the first n newest posts.... your pagination would also be a bit weird.


This does now all make me wonder, though, if using the Blog feature was even the best feature to use for this story. Would I have avoided all this hassle if I'd chosen a different type of SquareSpace section? Just wondering if there's a different feature that would still be able to present a side-by-side summary layout, and have pagination links at the bottom of each page, which wouldn't be subject to the blog post ordering.


I guess it depends how many of these "articles" there are in each series. You could consider portfolios, but you don't really get the side-by-side layout or excerpts. What you do get though is a completely free reign on the layout of each project and can order the projects within each portfolio as you wish.


If you did it like this you could just write up each section directly in the project page or you might also have an unlisted blog page that kept all the articles in and then use summary blocks to insert them into sections within the project page. So have a portfolio project for the TRS-80 repair, and then take people through it as a single story. big splashy headline, sections that take them through the concept and then use summary blocks to put the full blog articles in. if you wanted to break that story up into "acts" you could tag your blog posts and filter multiple summary blocks to show just the relevant tags. (note: summary blocks would still have new content first so you'd need some similar code to get those the right way round.

does anyone know if its possible to rverse the order of instagram posts within your squarespace website? i have a narrative work and i want the oldest post to be the one at the top and the newest at the bottom. any help would be appreciated ?


Not meaning to bump an old thread but for anyone trying to solve this problem in future I was able to pretty easily reverse the order of hundreds of blog entries arranged with the masonry design using the universal filter plugin.



This is a paid plugin and maybe overkill if you dont intend to add any filters but for the sake of having all the options it was simple as adding one line to the filter config.










I've been trying to wrap my head around SE-0244: Opaque Result Types and recently I had some realizations that helped me understand the proposal better. I noticed I'm not the only one confused about it, so I thought I'd write down some things that might help others to get a better grasp of the concept as well.


In doing so, I'd also like to try and rebrand opaque result types, or at least the underlying mechanism, to something I'm calling 'reverse generics'. I think viewing this all from a slightly different perspective helps a lot in understanding the concepts involved.


Reverse generics, as I'm calling it, is more or less the same concept as normal generics, but in a different direction as we all are familiar with. Many of the things involved work exactly in the opposite way.


The first step is already possible in the language, but for the second step we need some new syntax. I will use a caret (^) as prefix for reverse generic type parameters. This means that the generic type parameter T from the example will change to a reverse generic type parameter ^T.


Before we go to the reverse example, let's explain what a reverse generic type parameter is. A reverse generic type parameter is similar to a normal generic type parameter, the difference being who decides what the concrete type of the parameter will be. With normal generics, the caller selects the concrete type for the parameter, but with reverse generics the callee selects the concrete type.


With a normal generic function we normally say that the function is generic over its generic parameters. However, with reverse generics it's not the function itself that is generic. With reverse generics it is actually the caller of the function that will become generic. The following can be said about our examples:


What's important as well is that generic types are placeholders for concrete types and they don't suddenly change to a different type in the same context. So, just like the following is not possible with normal generics:


Note: This is the major difference in usability compared to existential types. An existential type can be a different concrete type every time. If the callee function would return an existential, then it is not known whether the two calls to callee() actually return the same concrete type. You would have to open up both existentials and make sure they are both the same concrete type before it would be possible to add them together.


The same is true for reverse generics, but remember that with reverse generics it's not the callee that is generic, but it's the caller that is generic. This means that if the compiler has enough information, it is the caller function that can be specialized. If the functions are defined in different modules, then the caller function cannot be specialized, because the compiler does not know which concrete type will be returned from the callee function. (note: For simplicity I'm not taking inlining into account here)


Note that when makeCollection is called with an Int element, it will return an Array of Ints, but when makeCollection is called with a String element, it will return an Array of Strings. This does not correspond with what we said earlier, that reverse generic types don't change. Well, this is a little bit more nuanced. The reverse generic types are fixed with respect to the normal generic types of the function. So, for every call to the makeCollection function where T == Int, it's still the case that the concrete type of the returned C is always the same. This means that the following works properly:


The syntax that we've used will naturally work with existing syntax for where clauses, which makes it possible to constrain types in more complicated ways. When looking at the previous example, which returns a collection, one thing to note is that even though the function always returns a collection with elements of the type that the caller requested, it does not promise that. The caller cannot be sure that it actually receives a collection with the requested type of elements. We can easily solve this with a where clause:


Instead of adding the concept of reverse generic type parameters, the proposed opaque result types syntax uses the 'some' keyword to basically declare an anonymous reverse generic type parameter. After the 'some' keyword, the constraints of the result type follow. Our earlier example of the makeCollection function without where clause can easily be translated into the proposed syntax for opaque result types:
