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 As         


        

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.
