I think the first step is to create and add the default configuration options .eslintrc file to my project. I’m not! You know it’s not fair, “mixed spaces and tables” is not an error, not even a warning. But they say “ERROR” in parenthesis. And many such things…
I understand your frustration. Since there are as many possible options as there are projects, it is not possible to create a one-size-fits-all configuration. However, there are many popular rules such as https://www.npmjs.com/package/eslint-config-airbnb and https://www.npmjs.com/package/eslint-config-standard that aim to It is the best overall coordination. a set of exercises. A project that hasn’t been coded against linter before can be a pain to adapt to, but it can also be worth it. Note that you can also start with a few rules and enable more in the future if you want.

For example, you can use module.exports = } to disable the console. Alternatively, you can expand the recommended configuration and disable the rules you need (https://eslint.org/docs/rules/). If you find the ribbon annoying, you can also turn it off completely in preferences. Full documentation can be found at https://eslint.org/docs/user-guide/configuring. – You understood this because you were mentioned. Reply to this email directly, see it in or mute the thread .
If you use any code editor, you can solve the errors effectively. Let’s take a look at the Visual Studio code editor example below.
In the paragraph above, you can see that I intentionally removed the parenthesis before the semicolon. VS Code is smart enough to tell you when you’re missing the closing braces. You can also see that the index.js file on the left is red, indicating a code error.
In the code snippet above, you can see that I misspelled the name of the alert function. But VS Code doesn’t say anything! In this case, you may run your code without realizing your error and find that the browser doesn’t display a warning.
Browser Errors Were Logged To The Console
Run your code. When the browser opens, you will see that your function is not working. In the above case, the warning box is not displayed because the function name is misspelled. To find the error, open the browser’s developer tools. You can find it in the browser menu or press F12 to open it.
There you will find the console tab. Click on it and you will find the error. Correct the code error by reading the instructions provided in the console.
In the case of the alert function, the misspelling caused an error that was logged in the Chrome browser’s console window.
.’ We know we misspelled the name of the alert function. No function is defined with alarm name. Fix it. A pop-up will appear.
For those of you who are completely new to programming, a bug is when your code doesn’t work correctly or as expected. The process of identifying, finding and correcting errors is called debugging.
How To Handle Errors In React
The reason debugging is difficult for beginners is that it is not clear where to start debugging.
Many of the tutorials you follow are pre-made and modified, so you will rarely run into obstacles. However, building real projects is very different from managed projects because bugs are dealt with at every stage of the project.
Advanced Features: Error Handling
This then begs the question, “If I’m always stuck, how can I fix the errors myself?”
The solution is as follows: we use the read-seek-ask method. Read-Search-Query is a step-by-step method for solving programming problems. This means that when you encounter coding, you read the documentation and error messages, Google the problem, and ask the developers for help and guidance.
Let’s say we want to create a simple function that turns text red when a button is clicked. Here is the sample code:
When we saved the changes and ran the code, we noticed that it did nothing. What happened? There is a bug in our code! To fix the problem, do the following.
When you open the developer tool, click on the console tab at the top of the window and from here you can check if there are any errors and if so, it points to the source of the problem.
Here is a screenshot of the first example of the error when you click on it in the Chrome Developer Tools console tab.
To view the location of the error, click the Source tab in Chrome’s Developer Tools window. We found that the problem was that we added an extra closed clip
To avoid such small errors, consider using Linting. Linting is the process of checking your code for errors before saving your changes and running your program. The most popular tool used by developers is ESLint. You can use it with almost any text editor or IDE.
. We don’t know what it means, and to understand the problem, we open Google search (or any search engine) and copy and paste the message into the search bar and see the results.
Most of the time, Stack Overflow appears in the search results and we open one of its links to read them and find possible solutions. To save time, we chose this.
. Therefore, the “#” hash is not needed. If we want to use the hashtag, we have to change it
The main advantage of problem hunting is that no matter what coding problem you are facing, chances are that someone has already faced the same problem and found a solution.
In most cases, you are likely to solve the problem by following only the first two steps. However, sometimes you are stuck even after spending a long time searching for a solution
