Uncaught SyntaxError: Unexpected token <
jsonp = (url, callback) => {
var callbackName = 'jsonp_callback_' + Math.round(100000 * Math.random());
window[callbackName] = function(data) {
delete window[callbackName];
document.body.removeChild(script);
callback(data);
};
var script = document.createElement('script');
script.src = url + (url.indexOf('?') >= 0 ? '&' : '?') + 'callback=' + callbackName;
document.body.appendChild(script);
}
componentDidMount() {
this.jsonp('https://www.naver.com', function(data) {
alert(data.meta.description);
});
}
But I get:
Uncaught SyntaxError: Unexpected token < error...
How can I resolve this?
In your .babelrc file
{
"presets":[
"react-app"
]
}
And then npm install --save-dev babel-preset-react-app
This is what create react app uses and is mostly updated to handle the latest syntax.
