• how return response asynchronous call? 21 answers

i'm trying promisevalue in renderselect. (in tmp)

the thing i'm getting promise, normal behavior. don't understand how values inside promise can work them.

i have apiservice class follows

handleresponse(response) {   if (response.status >= 200 && response.status < 300) {     return response.json();   }   return response.json()     .then((res) => {       throw new error(res.message);     },     () => {       throw new error();     }); }   get(url) {   return fetch(`${this.api_url}${url}`, {     method: 'get',     headers: this.headers,   })     .then(response => this.handleresponse(response)); } 

and .jsx this

const getoptions = (contractor_employee_id) => {   const apiservice = new apiservice()   return apiservice     .get(`some_url`)     .then(       response => {         return ["toto", "tata", "titi"]     },     err => (console.log("failed"))     ); };  const renderselect = (field) => {   const tmp = getoptions(field.id)   console.log(tmp) 

promises asynchronous. , if want return promise result in synchronous way, use async / await.

const renderselect = async (field) => {     const tmp = await getoptions(field.id)     console.log(tmp) }
