React.js

const firebaseConfig = {
        apiKey: <`apiKey`>,
        authDomain: <`authDomain`>,
        databaseURL: <`databaseURL`>,
        projectId: <`projectId`>,
        storageBucket: <`storageBucket`>,
        messagingSenderId: <`messagingSenderId`>,
        appId: <`appId`> 
            };

(step3) after create firebaseConfig object RUN (Firebase) function

let Fire=Firebase(firebaseConfig)

Insert

(part-1): After follow upper code then code write it :(this code for random keys)

--random keys means =your data will be save with random firebase keys

let Fire=Firebase(firebaseConfig)

Fire.child(<`Enter keys:string`>).push(<`Your_data`>,function(err){
    if(err)console.log("error")
    else console.log("save")
})
