Liferay AMD Loader doesn't support arrow function

I tried to use the arrow function in my react application but in deployed time, I got an error with the arrow function, the arrow symbol wasn't resolved.

Arrow functions are not something that must be “resolved”.

If you are targeting an environment that doesn‘t support ES2015 (called also “ES6”) features such as arrow functions, you need to transpile them. Old browsers have this problem. You can use Babel for this kind of issues.

Can you paste here the error you found? Probably you are missing a build step, and ES2015 code is being minified in the Portal (which supports only ES5 code).

I use "clean" in the Gradle module option and deploy it again and it works.
thank you @yuchi
