getting 3 console.logs #1
Description
I am getting 3 console logs I dont know why. I tried everything hooks/classes inside outside component and it doesnt work.
import React, { useEffect, Component } from 'react';
import ContextState from './context_state_config';
import history from './utils/history';
import ReactGA from 'react-ga';
import { observe } from 'react-performance-observer';
ReactGA.initialize('UA-144556525-1');
history.listen((location) => {
ReactGA.pageview(location.pathname + location.search);
});
var observer = observe(measurements => {
console.log(measurements);
});
class App extends Component {
// var observer = new PerformanceObserver(list => {
// list.getEntries().forEach(entry => {
// // Display each reported measurement on console
// if (console) {
// console.log("Name: " + entry.name +
// ", Type: " + entry.entryType +
// ", Start: " + entry.startTime +
// ", Duration: " + entry.duration + "\n");
// }
// })
// });
// observer.observe({entryTypes: ['resource', 'mark', 'measure']});
// performance.mark('registered-observer');
//
// function clicked(elem) {
// performance.measure('button clicked');
// }
render() {
return(
<div>
React
<ContextState />
</div>
)
}
}
export default App;
