Callbacks
Callbacks
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
Validation of javascript forms - name, password, password retype validation and Number Validation
Validation of javascript forms - name, password, password retype validation and Number Validation
It is critical to check the user-submitted form since it may include incor- rect information. As a result, validation is required to authenticate the user. Because JavaScript allows form validation on the client side, data processing is faster than server-side validation.15 JavaScript form validation is preferred by the majority of web developers. We can validate name, password, email, date, cell numbers, and other data using JavaScript. https://chat-to.dev/post?id=12 #javascript #web #programmer

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

why node.js makes me uncomfortable
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

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 (

I don't like using frameworks in my applications
i've been programming for some time and i've always had a solid command of the language i program in. will i have a problem creating complex and scalable applications because i don't use frameworks?

@FrozenCorgi my target audience is certainly portuguese-speaking, but I feel that even with the promotion on portuguese sites, I still register very few subscribers. and this has made me uneasy. is there something missing from the site or is it the niche that isn't very good? that's why I'd like to get some help and see what I really need to change on the site, or what strategy I need to use to change this paradigm.
@DmMacniel that's right. i've been getting better at it and bringing in more and more new tools. thanks
@DmMacniel thank you (y)
@DmMacniel php and javascript. the problem is that many people advise me not to use php. but i think that this language is just as powerful as any other language.
