I just startet learning React Native an got a problem.

i fetch a php file from my server and need to add a ID parameter to the url. the ID parameter is saved in a const.

How can I add my const to the end of the fetch url?

const Round = 1;

return fetch('http://myurl/data.php?ID=')

All you need is to concatenate the Round variable.

const Round = 1;
return fetch('http://myurl/data.php?ID='+Round);

You may also use Template literals

return fetch(`http://myurl/data.php?ID=${Round}`);

Use template literals:

const round = 1;
return fetch(`http://myurl/data.php?ID=${round}`);

Note: regular variables should have lowercase names, by convention.

Just put const variable at the end

For Example : 

const Round = 1;

return fetch('http://myurl/data.php?ID='+Round)
