javascript - react :Parsing error: await is a reserved word

Question

./src/App.js

Line 15: Parsing error: await is a reserved word

13 |   getWeather = async=()=>{
14 | 
15 |     const api_call = await fetch('http://api.openweathermap.org/data/2.5/weather?q=Manchester,uk&appid=${API_KEY}');
   |                      ^
16 | 
17 |     const data = await api_call.json();

如何消除这个错误？

Answer 1

由于您是这门语言的新手，我建议您不要使用这种方式。这就是所谓的箭头函数。

async () => { /*...*/ };

// same to

async function () { /*...*/ };

并将其与参数一起使用:

async (param_1, param_2) => { /*...*/ };

// same to

async function (param_1, param_2) { /*...*/ };

就您而言，问题可能来自

// remove "=" character after "async" keyword here
async=()=> { /*...*/ }

希望这有帮助!
