format doesn't works

[temuccio]

Hi all,
I have interested to use date-fns in my react-native project.
I use react-native version 0.62.2 and date-fns version 2.16.1.
after the import format such as
import {format} from 'date-fns';
I have try this example:

console.log('pre date');
var result = format(new Date(2014, 1, 11),'MM/DD/YYYY');
console.log.og(result);
console.log('after date');

The console print "pre date" but after the code is blocking (without error).
I have try also

var result = format(new Date(),'MM/DD/YYYY');

but I have the same problem.
Where I wrong?

Thanks

I did a quick copy and paste and was getting an error with your format() method, specifically the format argument.
Try var result = format(new Date(2014, 1, 11), 'MM/dd/yyyy');
