In {{glossary("JavaScript")}}, a block is a collection of related {{glossary("statement","statements")}} enclosed in braces ("{}"). For example, you can put a block of statements after an {{jsxref("Statements/if...else","if (condition)")}} block, indicating that the interpreter should run the code inside the block if the condition is true, or skip the whole block if the condition is false.
