The Art of Nesting

Sometimes experienced developers chain several ternary operators together. This can look beautiful if code hygiene rules are followed.

1. When is this appropriate?

When you need to choose one of three or four values based on a simple check:

let access = (role === 'admin') ? 'Full' :
             (role === 'user')  ? 'Limited' :
             'Guest';

2. Rules for Survival

1. Vertical alignment: Write each case on a new line.
2. Simple conditions: Don't write complex formulas inside a ternary.
3. Limit: If there are more than three branches — urgently switch to if...else or a lookup object.
