No issue here to me. You cannot use class in React components. Use className instead. For example here:. You have methods that don't return anything in some cases. Your methods should always return a component or at least nulle. In summary, I really recommend to go back a step and start with something more basic and ideally find a good editor e.

No issue there to me. But I don't know where to look anymore. Any idea, please? Thanks for your help. You won the Four Green Leaves Title! Note this comes with some pitfalls. And you get this error when exactly? When the page loads, when you click on a button etc? This happens when the page loads. So I just see this error message.

Linting is broken for entire file, no other errors are shown even though they exist, and autofix on save does not work. Mostly just specifics about globals and rules, that all comes from airbnb, nothing unexpected. Here's the rest. Adding babel-eslint solves the issue. The arrow functions are still experimental and not added to ESLint. Probably why it throws an error. Anyway, adding babel-eslint solved it for me too. ChampIsMe parser: babel-eslint at the top level in your eslint config should do the trick, see euharrison 's earlier comment for an example.

It throws the error on windows but not osx. It looks to be a windows issue, sadly. I get this error on osx. Try 2. Pretty sure that is the case. I get this error on eslint 2. On OSX it seems to work for 2. Yep, it basically turned off babel-eslint for everyone. If you don't don't get unexpected token there would of been an issue or you don't need babel-eslint haha. Anyone got a clue why? I'm still seeing the error. I'm using eslint-loader which could have to do with it, it looks like more people are seeing the issue as well. I've gone back and forth, uninstalled everything concerning eslint locally and globally, then went back and tried installing 2. I'm glad that version 2. I must've tried too many things at once when I was testing different versions. I'll just use 2. Thanks hzoo. Skip to content.

JavaScript Error Handling: Unexpected Token


Unexpected Token errors are a subset of SyntaxErrors and, thus, will only appear when attempting to execute code that has an extra or missing character in the syntax, different from what JavaScript expects. Like most programming languages, JavaScript tends to be fairly particular about its syntax and the way it is written. JavaScript code is parsed from left to right, a process in which the parser converts the statements and whitespace into unique elements:. However, in situations where the syntax is wrong often due to a typo, we might come across an Unexpected Token error, indicating that the parser thinks there should be another element in a particular place, rather than the token that it found there. For example, here we have a very simple call to the Math. By including that extra comma in our method call, JavaScript expects a third argument to be included between that final comma and the closing parenthesis. The lack of that third argument is what causes the Unexpected Token error, and is why JavaScript is none too pleased. Often, Unexpected Token errors are just due to an accidental typo, but to help avoid these, it is quite beneficial to use a code editor that provides some form of auto-completion. This is particularly useful when forming basic logical blocks or writing out method argument lists, since the editor will often automatically provide the necessary syntax surrounding your code snippet. When JavaScript parses this, it expects that brace character, but instead it gets the else :. The reason for this is that the parser finds our SyntaxError and reports on it before our catch block is even evaluated. Such Unexpected Token errors can be caught, but doing so typically requires execution of the two sections problematic code versus try-catch block to take place in separate locations. To dive even deeper into understanding how your applications deal with JavaScript Errors, check out the revolutionary Airbrake JavaScript error tracking tool for real-time alerts and instantaneous insight into what went wrong with your JavaScript code. No more searching through log files. Capture every bug and error in your app with just a few lines of code. The Technical Rundown All JavaScript error objects are descendants of the Error object, or an inherited object therein. The SyntaxError object is inherited from the Error object. The Unexpected Token error is a specific type of SyntaxError object. When Should You Use It? JavaScript code is parsed from left to right, a process in which the parser converts the statements and whitespace into unique elements: Tokens : These are words or symbols used by code to specify the logic of the application. These are reserved by the JavaScript engine, and thus cannot be used incorrectly, or as part of variable names and the like. Line terminators : As the name implies, a new line termination character.

Hi slim-hmidithanks for this issue. I think this is working as designed, although I understand your frustrations here. I don't know of one off the top of my head. I found this parser eslint-plugin-json but I don't know if it the suitable one. But if the default parser parses only the js files and we could lint a json extension with --ext option, we should modify the default parser to take a consideration the json files or add a plugin to parse them in the eslint configuration. I don't find it normal to add json extension when lint files then I discover the default parser does not do the job. Maybe I said stupid things but I think by default it should parse all the allowed extensions. I can understand how it might seem unintuitive when you're starting out and trying different CLI options; but the behavior you've observed is in line with the design and architecture of ESLint. Unfortunately, it looks like there wasn't enough interest from the team or community to implement this change. While we wish we'd be able to accommodate everyone's requests, we do need to prioritize. We've found that issues failing to reach accepted status after 21 days tend to never be accepted, and as such, we close those issues. This doesn't mean the idea isn't interesting or useful, just that it's not something the team can commit to. Skip to content.
