Assign Global Variable to Function Parameter

Question

For example:

var obj = {};

$.getJSON('data.json', function(data) {
    obj = data;
});

console.log(obj)

The console then outputs an empty object instead of whatever value data was.

in your code

$.getJSON('data.json', function(data) {
    obj = data;
});

is an asynchronous function, the code

console.log(obj)

does not wait for it to stop executing and hence you cannot see anything
