var setNonEnumerableReadOnly = require( '@stdlib/utils/define-nonenumerable-read-only-property' );

function Foo( name ) {
    if ( !(this instanceof Foo) ) {
        return new Foo( name );
    }
    setNonEnumerableReadOnly( this, 'name', name );
    return this;
}

var foo = new Foo( 'beep' );

try {
    foo.name = 'boop';
} catch ( err ) {
    console.error( err.message );
