Struct boa::syntax::ast::node::try_node::Try

pub struct Try { /* fields omitted */ }

The try...catch statement marks a block of statements to try and specifies a response should an exception be thrown.

The try statement consists of a try-block, which contains one or more statements. {} must always be used, even for single statements. At least one catch-block, or a finally-block, must be present.

More information:

• ECMAScript reference
• MDN documentation
