Until then I had not needed the effect, so I searched - unsuccessfully - how to do it. The examples I found were useless to me, because they were very specific to the cases studied. Here is my version of how to capture such parameters./post/filter-json-data-from-a-key/Mon, 18 May 2020 16:00:00 +0000/post/filter-json-data-from-a-key/You have a large flat JSON made up of many objects, made up of several key-values ​​(normal). You need to recompose that JSON so that the objects are filtered by one of its keys. It may sound extremely complex but trust me, with this feature you will reconsider. Let’s start with this sample: var miData = [ { category: 'animales', name: 'Perro', pic: 'http://url.a/la/foto' }, { category: 'cosas', name: 'Silla', pic: 'http://url./post/forget-about-concat-and-start-using-concat/Mon, 18 May 2020 16:00:00 +0000/post/forget-about-concat-and-start-using-concat/It may sound crazy but Array.prototype.concat()from javascript I think it is the worst implementation that we can find in any modern language to concatenate variables or portions of texts to another text string. We can concatenate in two ways: var mensaje = "Buenos días, "; var nombre = "Junior"; console.log( mensaje.concat(nombre) ); // RESPUESTA: "Buenos días, Junior" var mensaje = "Buenos días, "; var nombre = "Junior"; console.log( mensaje + nombre ); // RESPUESTA: "Buenos días, Junior" Don’t they look good?/post/saving-data-in-localstorage/Mon, 18 May 2020 16:00:00 +0000/post/saving-data-in-localstorage/Along with the arrival of HTML5 we have seen many improvements in the way how to save data in the user’s browser, such as localStorage and sessionStorage , the latter coming to replace the obsolete cookies. Both cookies, sessionStorage and localStorage have limitations on the length of data that we can have. Thus, cookies only allow up to 4095 bytes to be saved, while sessionStorage and localStorage support between 8MB and 10MB depending on the browser (just the true beauty of these), so that we can transfer data between pages temporarily while the user browses our site (sessionStorage) or we can leave locally saved data indefinitely -or until the user cleans their browser- (localStorage)./post/search-in-a-text-string-with-in/Mon, 18 May 2020 16:00:00 +0000/post/search-in-a-text-string-with-in/After JavaScript (EcmaScript), Python is my second favorite programming language. It has a very low learning curve, making it quite intuitive compared to other languages ​​and its list of basic keywords is short. Any individual can quickly adapt, even those who have never written a line of code (but who understand English). One of the basic Python keywords is in, used to search for portions of text within a text string, list, dictionary or tuple./post/subtract-or-add-hours-to-a-date/Mon, 18 May 2020 16:00:00 +0000/post/subtract-or-add-hours-to-a-date/We have all seen you obliged to save the date / time of a transaction. For security, it is preferable to make this calculation in the back-end, but if security is not so important, here is the tool you need to subtract or add hours or days to the current date. First the following function, which will allow us to show the hours, minutes or days of the date with two characters instead of one:/post/templates-for-lists-without-templates-engines/Mon, 18 May 2020 16:00:00 +0000/post/templates-for-lists-without-templates-engines/I must admit that it has always been heavy and boring to integrate resources not programmed by me in my work stack, so many of the functions and utilities are my responsibility. Some time ago we were hired by a client to create a project that required a panel to create and update content, a mobile application and a web application. One of the strengths of this project was the lists since it involved a product catalog.
