JavaScript Conditional Operators

🎯 한 줄 통찰 (One-line insight)

Conditional statements run different code depending on true/false conditions — JavaScript provides if, else, else if, switch, and the ternary (? :) shorthand. [S1]

🧠 핵심 개념 (Core concepts)

• Conditional statements branch on conditions — they let you perform different actions for different conditions. [S1]
• if — use if to specify a code block to be executed if a specified condition is true. [S1]
• else — use else to specify a code block to be executed if the same condition is false. [S1]
• else if — use else if to specify a new condition to test if the first condition is false. [S1]
• switch — use switch to specify many alternative code blocks to be executed. [S1]
• Ternary (? :) — use (? :) (ternary) as a shorthand for if...else. [S1]

🧩 추출된 패턴 (Extracted patterns)

• Pick the right branching construct — single decision → if/else; chained conditions → else if; many discrete cases → switch; one-line value choice → ternary. [S1]
• Ternary as expression — the ternary form condition ? expression1 : expression2 returns a value, unlike statement-only if. [S1]

📖 세부 내용 (Details)

Conditional Statements [S1] Conditional statements allow you to perform different actions for different conditions — running different code depending on true or false conditions. Conditional statements include:

• if — Use if to specify a code block to be executed, if a specified condition is true.
• else — Use else to specify a code block to be executed, if the same condition is false.
• else if — Use else if to specify a new condition to test, if the first condition is false.
• switch — Use switch to specify many alternative code blocks to be executed.
• ternary (? :) — Use (? :) (ternary) as a shorthand for if...else.

Ternary (? :) syntax [S1] The page shows the ternary as a syntax template rather than a runnable named example:

condition ? expression1 : expression2

This page is an overview/index of the conditional constructs; the detailed runnable examples live on the dedicated pages it links to. A concrete named-variable ternary example was Not found in source on this page.

🛠️ 적용 사례 (Applied in summary)

This is an overview page; it points to the dedicated if, else, switch, and ternary pages where the working examples reside. No external project/commit applications found in the source.

💻 코드 패턴 (Code patterns)

Ternary shorthand for if...else:

condition ? expression1 : expression2
