Why is it difficult for you to master JavaScript

Compared with HTML and CSS, the JavaScript learning curve may appear steep. The following are some common reasons:

Information overload:

JavaScript has a huge ecosystem, including countless tutorials, frameworks and libraries, which is easy to be overwhelmed.

1. grammar and concept: If you have insufficient programming experience, the concepts such as closure, Promise or Async/Await may be difficult to understand.
Lack of practice:
2. It is not enough to watch the tutorial or read the guide. Without practical applications, concepts are difficult to consolidate. Skip the foundation:
Learning the high -level theme under the condition of not strong foundation will only make you more confused and frustrated.
3. The correct learning method
4. To effectively learn JavaScript, you need a structured method, give priority to practice, and gradually establish confidence. The following methods are effective: Master the basic knowledge:
Before learning the high -level theme, focus on understanding variables, data types, circulation, function and conditional statements.

step -by -step:

Just learn only one concept at a time. Before you are familiar with the native JavaScript, don't rush to learn the framework or library.

Repeated practice:

Writing code every day. Solve small problems, build small projects, and review your solution.
1. Test your understanding: Use test cases to verify your code. This can not only improve your problem solving ability, but also prepare for the actual scene.
2. Project practice: Construct practical projects to integrate multiple concepts. The project allows you to get a sense of accomplishment and leave a shiny mark on your work.
3. The recommended learning route diagram This is a long -lasting JavaScript learning route map:

First Week: Basic Knowledge

• Learn variables, data types and operators.
• Practice cycle and conditional statements.
• Written a function and understand the scope of the action.
• It is recommended to practice: write a function to check whether a number is a prime number.

The second week: ES6 features

• Learn Let/CONST, Template Noodles and arrow functions.
• Understand deconstruction, expansion/remaining operational symbols and modules.
• Familiar with Promise and Async/Await.
• It is recommended to practice: Use ASync/Await to write a function to get data from the API.

Third Week: Array, object and text

• Master the array methods, such as Map, Filter, and Reduce.
• Object: Create, update and traverse objects.
• Practice string operation skills.
• It is recommended to practice: Create a function to count the number of times each word appears in the string.

Fourth Week: Construction project

• By constructing actual projects to consolidate your knowledge:
  • A application to the item.
  • A simple scientific calculator.
  • Simple weather application using API.
• Use test cases to verify your code.
• It is recommended to practice: build a scientific calculator that uses all the mathematical functions you have learned.
