You have mastered HTML and CSS, and even built a simple website, and now start to learn JavaScript. However, a few weeks or even a few months have passed, and you still feel confused? Don't worry, you are not alone!

This article will guide you how to learn JavaScript quickly and efficiently, and avoid being exhausted in the early stages of learning.

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.
