We can achieve asynchronous programming in JavaScript if we use the callbacks. A callback is a function that is passed as an argument to another function. The idea of the callback function is ‘I will call you back later’. You should know that the functions in JavaScript are executed in the sequence they are called, not in the sequence they are defined in. Okay, without confusing you, I will start from the beginning, why sequence control is so important in JavaScript. The sequence of control allows us to control the sequence when a function needs to be executed. For example, let us say that we want to create a function that will do some basic arithmetic operation like the sum of two integer numbers. After the function returns the result, we want to call another function to display the result to the user. So now we have two functions, one mainly for calculation, and the other is to display the user the result. Therefore we know their sequence of execution. Of course, you cannot start showing the results without first calling the calculation function. Here is the entire example: https://www.chat-to.dev/post?id=13
use any fonts you like on your web pages thanks to this recipe.
Although web browsers come with a reasonable range of default fonts, they don’t always provide the look you need for a particular web site. In such cases, you usually must resort to calling up a graphic editor and creating logos or headlines there. However, with this recipe all you have to do is upload the TrueType fonts you wish to use to your web site and you can then display text in these fonts by having the GD library convert it on the fly to GIF images. https://chat-to.dev/post?id=9#php#backend#programming
When accepting user input for redisplay, and particularly if it will be inserted into a database, it’s important that you sanitize the input to remove any malicious attempts at hijacking your server, or otherwise injecting unwanted MySQL commands, HTML, or JavaScript. https://chat-to.dev/post?id=6
why node.js makes me uncomfortable
I've always programmed with php for the web and during that time I've never needed to download packages (like npm) and update them. When I needed a specific function, like sending emails, uploading files or making my application drier, I just had to look at the documentation and implement it. But with node.js it doesn't work like that, and that bothers me. If I'm wrong, please correct me
could someone mention some social networks on the deepweb? i'm very interested in spreading the word about my applications there. i know it's a pretty toxic environment, but it can also be an open door to new challenges.
How do you start your applications once the idea has been created? Do you implement the screens first and then work on the backend, or do you build the backend first and then take on the visual part (the screens)?
I do model first, then backend, then I normally pause to get a bit of the front end done and do some testing.
Then I tweak from there. It’s kind of like I “sneak up” on my final final solution with adjustments to the MVC.
That’s the process is if I’m building something and already have a clear idea of what stakeholders want. If that’s unclear, I start with mockups of screens and ship them off for approval.
Start with a dummy backend with hardcoded values, then make a frontend to display and manipulate thos values. Once that’s done, create the real backend, and maintain from there
