Struct boa::syntax::ast::node::break_node::Break

pub struct Break { /* fields omitted */ }

The break statement terminates the current loop, switch, or label statement and transfers program control to the statement following the terminated statement.

The break statement includes an optional label that allows the program to break out of a labeled statement. The break statement needs to be nested within the referenced label. The labeled statement can be any block statement; it does not have to be preceded by a loop statement.

• ECMAScript reference
• MDN documentation
