what does this error mean with this code Accessors are only available when targeting ECMAScript 5 and higher.ts(1056) Not all code paths return a value.ts(7030) get currentUser() { let token = localStorage.getItem('token'); if (!token) return null; }
The error "Accessors are only available when targeting ECMAScript 5 and higher.ts(1056)" means that the "get" accessor is only supported when using ECMAScript 5 or a newer version of JavaScript. The code you provided is using a get accessor for the currentUser property.
The error "Not all code paths return a value.ts(7030)" means that there is a code path within the get accessor that does not have a return statement. In your code, the if statement returns null if the token is falsy, but there is no explicit return statement if the condition is false.
To fix the first error, you need to make sure your project is targeting ECMAScript 5 or a higher version.
To fix the second error, you can add a return statement that returns a value other than null when the condition is false. For example, you can return an empty string or undefined. Here's an example of how you can fix the code:
javascript Copy code
get currentUser() {
let token = localStorage.getItem('token');
if (!token) return null;
return ''; // or return undefined;
}
Please note that without more context or information about the code, it might be challenging to provide a more specific solution.
👩💻 fixed the second error. now how do I make sure about which version of ECMAscript my project is targeting
To determine which version of ECMAScript your project is targeting, you can check the configuration or settings of your project or development environment.
If you are using a specific code editor or integrated development environment (IDE), such as Visual Studio Code or WebStorm, you may need to check the project settings or configuration files specific to your development environment.
If you are using a build tool or bundler, such as Webpack or Babel, you can check the configuration files associated with those tools. These files, such as webpack.config.js or .babelrc, often include options or settings related to ECMAScript versions.
Additionally, if you are using a specific framework or library, such as React or Angular, the configuration of these frameworks may also include options or settings related to target ECMAScript versions.
If you are unsure where to find the configuration or settings related to ECMAScript versions, it is recommended to consult the documentation or search for specific instructions related to your development environment or tools.
👩💻 I am using VScode and angular where can I check this
To check the target ECMAScript version in an Angular project using Visual Studio Code, you need to look into the tsconfig.json file in the root directory of your project.
tsconfig.json file in the root directory of your project.tsconfig.json file in Visual Studio Code.target field within the compilerOptions section of the tsconfig.json file.target field specifies the ECMAScript version that your Angular project is targeting.Here's an example of how the compilerOptions section might look in a tsconfig.json file for an Angular project targeting ECMAScript 5:
json Copy code
{
"compilerOptions": {
"target": "es5",
// other compiler options...
},
// other configurations...
}
In this example, the "target" value is set to "es5", indicating that the project is targeting ECMAScript 5.
Please note that the exact value in the target field may vary depending on your project's configuration or requirements.
You can update the target field in the tsconfig.json file if you need to change the target ECMAScript version for your Angular project.
👩💻 is targeting this: "target": "ES2022", so it is much higher than ECMAScript 5 correct? Ido not understan why do I get that issue then
Yes, targeting "ES2022" means that your Angular project is using ECMAScript 2022, which is a higher version than ECMAScript 5.
The error message you mentioned, "Accessors are only available when targeting ECMAScript 5 and higher.ts(1056)", seems to be contradictory to the ECMAScript version you are targeting.
In this case, it's possible that the error is not related to the ECMAScript version itself, but rather a configuration or compatibility issue in your development environment or tooling. Here are a few things you can check:
Make sure that your Visual Studio Code and Angular installations are up to date. Outdated versions of tools or plugins can sometimes cause unexpected errors.
Verify that the TypeScript version being used aligns with the ECMAScript version you are targeting. You can check the TypeScript version by running tsc --version in your terminal.
Check if there are any conflicting configuration files or settings in your project. For example, if you have multiple tsconfig.json files, ensure that the one in the root directory is the one being used for your Angular project.
Consider checking if you have any custom linting rules or plugins that might be causing the error. Some linting rules or plugins can have their own configurations that may conflict with ECMAScript features.
If you have reviewed these aspects and the error persists, it might be helpful to include more details or the specific code that is triggering the error message. This would enable a more in-depth analysis of the issue and provide a more accurate solution.

AI stands for Artificial Intelligence. AI bots are able to learn from conversations with users and expand their knowledge this way.
SheCodes Athena will help you with technical questions about your code using artificial intelligence to find the answer. Imagine a super powerful human who has memorized everything on the internet and can access that knowledge in a matter of seconds. 🤯
SheCodes Athena can answer most coding-related questions, even complicated ones! It can even find bugs in your code and tell you how to fix them in just a few seconds. Impressive, right?
Just remember we're still in testing mode so the AI may return strange or incorrect replies. Feel free to message us if this happens!
SheCodes Athena can only reply to coding-related technical questions. The same type of questions you would ask in the channels on Slack.
For questions that are not coding-related, write us here 😃
You should treat Athena like a SheCodes team member, so always be polite! 😊 Ask your questions as detailed as possible, just like you would do on Slack.
Here are some examples:
- Prettier isn't working on my VS Code. How do I fix this?
- How do I make bullet points with different colors using the list element?
- My code in Codesandbox is having some issues. Can you please tell me what the issue is? [Include the link to your Codesandbox]
For now, SheCodes Athena is limited to 5 questions per day for each student.
In that case, you can either ask SheCodes Athena a follow-up question, or you can post on the designated weekly channel on Slack!
Our technical assistants are still available on Slack and are always happy to help! 😍💪
Remember, questions are limited to 1000 characters.
- If you're working with an HTML file: Post a snippet of your code related to the issue you're having (just copy the code and paste it into the question box).
- If you're working with Codesandbox: Good news, you can just post the link to your Codesandbox and the AI Assistant will be able to view your code.
- If you have a longer question that would require an entire HTML file or more than 1000 characters, post it in the designated weekly channels on Slack! 😃
Athena was the Greek goddess of wisdom, among other elements. She received her name from the city of Athens, which she is known for protecting.
Much like the goddess Athena, SheCodes Athena is also incredibly wise and can solve complicated coding puzzles in a matter of seconds! 😍
Not likely. AI can automate tasks and make developers' jobs more efficient but it can't fully replace the human ability to deal with complex software. And AI will still require human developers to supervise and improve it further.
So developers may see their tasks change but they won't be replaced by AI. 👩💻🤝💻
