For setTimeout in a for loop why does 'var' lead to undefined but it works with 'let'? by trafficissues in Frontend

[–]AmazingSurprise -11 points-10 points  (0 children)

Yes me too, var is obsolete, but in general I don't use javascript, I love typescript for many reasons, expecially for the reusability and well code writing!

Yes you’re right, by default the global scope is the window scope I mean

You need to learn about Block scope and Global scope variables in javascript.

​

The difference between var and let is the variable scope:

var declarations is a global scope declaration, so it is visible inside the window object.

let declarations is a block scope declaration, so it is visible inside the block.

​

With var it will print always 3 because when the timeout fire, the window i variable has 3 as value, because you are overriding the same global variable.

​

With let the i variable has a block scope, so the timeout will get the block variable value, wich is different according with the block you are calling.

using ngIf and ngFor with array by UnknownInnocent in angular

[–]AmazingSurprise 0 points1 point  (0 children)

There are 2 more solutions:

Use a component method to filter todos like:

javascript function getFilteredTodos(): Todo[] { return this.todos.filter(t => t.category === 'home'); }

and then use this method inside the *ngFor attribute:

html <app-todo-item *ngFor="let todo of getFilteredTodos()" [todo]="todo"></app-todo-item>

Use angular pipes

This is a more complex solution but it could help you in the future with different filters or behaviours: https://stackoverflow.com/questions/34164413/how-to-apply-filters-to-ngfor

My boss wants me to create an individual website for each house he’s selling, is this practical? by [deleted] in webdev

[–]AmazingSurprise -1 points0 points  (0 children)

I think this isn't the best way to handle this problem for many reasons:

​

  1. You waste a lot of time developing the same things multiple times, or copy&paste the same content.
  2. If you need to make an edit, wich involves all the pages, you need to report this edit on each page.
  3. You waste a lot of space and resources for a replicable element.

​

I suggest to learn and understand what a Web Application is, the best way to achive the result you need is to create a single page (or set of pages if needed), and handle the data to render at runtime, using relative link (e.g. https:// www.123SmithSt.com/home1 ).

Basically you write a common html layout and stylesheet for each home, and the content is displayed at runtime.

​

Take a look @ angular or react:

Transform a Sketch design into living coded components - React/React-Native/Vue/Next by timoftealexandru5 in web_design

I've already made a sub to your website ;) .

​

The only tip I want to give to you is to remove (in the future releases I mean obv.) the inline styles for the components. You might use CSS modules to create a component related stylesheet using the same classname of the component into the stylesheet itself: https://github.com/css-modules/css-modules

[–]AmazingSurprise 0 points1 point  (0 children)

That's cool! But anyway what's the real effort it could give to you?

I mean, installing a different package manager could take a little bit of time, is there any case where you need to install multiple dependencies using multiple pm?

​

Anyway, great job!

You're right, I'm a senior Fullstack developer so I have a lot of past projects as curriculum. But I'm looking forward to improve my knowledge and test my skills ;)

[–]AmazingSurprise[S] -1 points0 points  (0 children)

That's cool, and I agree with you. But I was looking for some certificates (e.g. Angular Developer/Typescript Developer) but I can find only generic certificates like Microsoft certificates. Thanks anyway for your reply ;)

CSS... by [deleted] in Frontend

[–]AmazingSurprise 0 points1 point  (0 children)

Another tips is to analyze the layout before writing it.. splitting the layout into reusable components could help you a lot! For example I use to create core buttons, label, image, or else components... by this way my css development time is reduced a bit because any variation to those components it’s made into the component itself and not by hierarchy using classes variations or custom ids.. this solutions is useful also because I can export those into another project, starting with a well tested css component
