That’s a little snippet of code to set the
src(source) attribute of a Javascript include tag to/json?callback=loadJsonPhotos. Once that line of code runs, the browser will fetch the data from that URL and execute the script that returns. The data that script returns will be wrapped in a function like so:All you need to do to use that data is write a function called loadJsonPhotos that will be called once the data has loaded.
