Chain of Jquery Promises

Question

I have a simple chain of events:

1. Get Columns from a metaData table (async)
2. load selected columns (async)
3. render list

I used t

Answer 1

It should be something like:

function getColumnsFromMeta()
{
    var d = $.Deferred();

    // retrieve data in async manner and perform
    // d.resolve(columns);

    return d.promise();
}

function loadSelectedColumns(columns)
{
    var d = $.Deferred();

    // retrieve data in async manner and perform
    // d.resolve(data);

    return d.promise();
}

function render(data)
{
    // render your data
}

getColumnsFromMeta().pipe(loadSelectedColumns).pipe(render);
