Body
Some working code is on the bottom. But my poorly adapted code on the top goes into an infinite recursion loop. What is it I do not know about arrays? <pre><code>function recSubsets(soFar, rest) { if (rest===[]) console.log(soFar); else { recSubsets(soFar.push(rest[0])), rest.slice(1)); recSubsets(soFar, rest.slice(1)); } } function listSubsets(s) { recSubsets([],s); } listSubsets([4,9,3,77]) </code></pre> below is the working version for strings <pre><code>function recSubsets(soFar, rest) { if (rest==="") console.log(soFar); else { recSubsets(soFar+rest[0], rest.substring(1)); recSubsets(soFar, rest.substring(1)); } } function listSubsets(s) { recSubsets("",s); } listSubsets("cat") </code></pre> gives me: cat ca ct c at a t

2. COI added it to the bottom... It seems that my function is not treating an array like an array. And I don't see why not.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
