Struct boa::syntax::ast::node::block::Block

pub struct Block { /* fields omitted */ }

A block statement (or compound statement in other languages) is used to group zero or more statements.

The block statement is often called compound statement in other languages. It allows you to use multiple statements where JavaScript expects only one statement. Combining statements into blocks is a common practice in JavaScript. The opposite behavior is possible using an empty statement, where you provide no statement, although one is required.
