Here are some of the key concepts you need to learn, grasp, and the master at to be able to emerge as a successful programmer/web developer:
1. Dom Creation and Modification
The ability to create or modify elements on a web page facilitates programmer to create dynamic web pages. These pages can also change effortlessly based on user interaction.
2. Value vs. Reference
It is important for a programmer to understand the way in which arrays, functions, and objects get copied and passed into functions. Also, the reference being copied should be known. Understanding the fact that primitives are copied and passed via copying the value will also help.
3. Asynchronous Communication
A function retains access to scope that it was initially created in. Understanding what this allows to do is also crucial. Some of the functions include such as dynamic function generation, data hiding, and memorization.
5. Loops are Important
Loops are a key element to any programming language. These facilitate you to repeat blocks of code for any number of requisite times. So, this saves you from writing repetitive code. With loops, it is easier to iterate through data structures. A programmer should know precisely how, when and why to use loops.
6. Functions and Function Calls
Similar to loops, functions are a vital key programming concept. These are universal across most programming languages. With functions, you can encapsulate code blocks which can be used anytime later via calling the function.
7. Dev Tool Debugging
8. Prototypes & Inheritance
This is known to be one of the toughest concepts to grasp. The scope is categorized into two major types:
A variable is global when it is declared outside a function and can be virtually accessed anyplace within the code. On the other hand, the local variable is one that’s declared within a function. Also, it can be accessed only within that specific function. Now, these theories explain scope at its elementary level. It can get complex further. Hence, it is crucial to get a tight grasp on these concepts at initial stages to build a solid foundation and emerge as a successful web developer.
10. Conditional Statements
These are the fundamentals of a logic/decision making occurring within a code. Decisions made within code will be accomplished the certain type of conditional statement. This facilitates programmers to control what the code is undertaking based on varied variables and circumstances.
11. Events and Event Handling
