How to use await key word on react native?

Question

I tried to use await/async on react native,but I got unexpected token error.

I added the code blow in my javascript source file:

var value = await AsyncStorage.getItem('STORAGE_KEY'); 

My react native version is 0.15.0.

Do I need to add some configuration to use async/await?

Answer 1

I'm using async/await in my react native app and didn't have to do anything to configure or enable it in my project. My usage takes the form of...

async getCache(key){     try{         let value = await AsyncStorage.getItem(key);         return value.json();     }     catch(e){         console.log('caught error', e);         // Handle exceptions     }  } 

Note: If you use an await inside a function that is not explicitly declared with async, you'll end up with an Unexpected token syntax error.
