JavaScript Conditionals

Conditional Statements

Conditional Statements allow us to perform different actions for different conditions.

Conditional statements run different code depending on true or false conditions.

Conditional statements include:

• if
• if...else
• if...else if...else
• switch
• ternary (? :)

When to use Conditionals

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