JavaScript Ternary Guide
The ternary operator (condition ? ifTrue : ifFalse) provides inline conditional expressions in JavaScript. The guide walks through Ternary Basics. `const result = age >= 18 ? "Adult" : "Minor"`. Chain: `a ? b : c ? d : e`. Avoid nested ternaries — hard to read. Use for simple binary choices, conditional rendering, inline value selection. Prefer if/else or switch for complex logic. The guide is organized into 1 sections that build on each other, each pairing a prose explanation with runnable code. Related guides: Arrays, Strings, Numbers, Math, Date. This is one of 145 JavaScript guides on JS Reference — see the full list on the guides page.
