5 min readTo create a list of a certain depth in Haskell, you can use recursion to generate nested lists. One approach is to define a function that takes a depth parameter and recursively creates nested lists until the desired depth is reached. You can use pattern matching to handle different cases, such as when the depth is 0 or when it is greater than 0. By using this recursive approach, you can easily generate lists of any desired depth in Haskell.

4 min readIn a Shopify template, you can iterate through products using liquid logic. Liquid is the language used in Shopify themes to output dynamic content. To iterate through products, you can use a for loop in your template file.First, you will need to access the products object, which contains all the products in your store. You can do this by using the {{ collections.all.products }} liquid object.Next, you can use a for loop to iterate through each product in the collection.

6 min readTo subtract one array by another array in Swift, you can use the zip() function to iterate through both arrays simultaneously and perform the subtraction operation. For example, if you have two arrays named arr1 and arr2, you can create a new array by subtracting the corresponding elements like this:let result = zip(arr1, arr2).map { $0 - $1 }This will create a new array named result with the elements obtained by subtracting the elements of arr2 from the elements of arr1.

4 min readIn Laravel, closure is a way of creating anonymous functions that can be used as callbacks or stored in variables. Closures can be used for defining route callbacks, middlewares, and event listeners. They provide a way to encapsulate functionality and pass it around without needing to define a named function.In the context of routing in Laravel, closures are often used to define what should happen when a specific route is accessed.

4 min readIn Haskell, if you want to obtain a single integer value instead of a list of integers, you can use the head function to extract the first element from the list. For example, if you have a list containing an integer x, you can write "head [x]" to get x as a single integer instead of [x] as a list of integers. However, keep in mind that using head directly on an empty list will result in an error, so it's important to make sure the list is not empty before using this approach.
