1). Asynchronous Communication
AJAX It gives you the opportunity to dynamically load information onto your website without having to refresh the entire page. The advantage is that less data is sent from the server when only a section of the page needs to be changed. It also improves the user experience with faster loading times and the page doesn’t flicker every time something changes.
2) Dom Creation & Modification
The ability to create or edit elements on a web page allows you to create dynamic web pages that can change based on user interaction.
Loops are a key element of any programming language. Loops let you repeat blocks of code as many times as you want, so you don’t have to write repetitive code. Loops also allow you to iterate through data structures with minimal effort. Understanding how, when and why to use loops is an essential skill for any programmer.
4) Debugging development tools
All Web browsers have some sort of developer tool for debugging, even the one you’re currently using. If you’re using Chrome, right-click and select Inspect. You should see a “panel” at the bottom or right of the browser.
Maybe one one One of the hardest concepts for a new developer to understand is scope, and it’s an important concept to understand. There are two main types of public relations: global and local. When a variable is declared outside a function, it is considered global and accessible from virtually anywhere in the code. A variable declared in a function is considered local and can only be accessed within that function.
This is scope in its most basic form. And it can quickly become so much more. complex, but understanding these concepts as early as possible can help you build a solid foundation to advance on your journey to becoming a web developer.
6) Features and Functions Calls
Functions, like loops, are a fundamental and universal programming concept in most programming languages. Functions allow you to encapsulate blocks of code that can be used later by calling the function.
7) Conditional Statements
Conditional Statements These they are the basis of all logic/decision making that occurs in the code. If something is true, do it; If not, do this. Every decision made in your code is made using some type of conditional statement. This allows you to control what your code does based on different circumstances and variables.
8) Events and event handling
Most, if not all, of the code executed by a web page is triggered by some type of event. Some of the most common events are: page load, click, mouseover, etc.
9) Referencing variables, values and data types
Programming it’s all about data manipulation. and the treatment to be carried out. Variables contain this data. (Remember high school algebra? x = y + 3). X and Y are variables that can represent any number. While programming, we use variables to store data in different formats such as: B. Numbers, strings and boolean values.
These are considered as value of variables. Another type of variables are arrays and objects, which in the simplest sense are containers containing groupings of other variables (think of a carton of eggs as an array, and each egg is a variable containing a certain type of data). Arrays and objects are reference variables. Understanding the difference between different variables and data types can help you build a solid foundation for your journey to becoming a developer.
