Struct boa_engine::syntax::ast::node::declaration::function_expr::FunctionExpr

source · [−]

pub struct FunctionExpr { /* private fields */ }

Expand description

The function expression defines a function with the specified parameters.

A function created with a function expression is a Function object and has all the properties, methods and behavior of Function.

A function can also be created using a declaration (see function expression).

By default, functions return undefined. To return any other value, the function must have a return statement that specifies the value to return.
