Force V8 to use fast properties for an object
Use %HasFastProperties(object)
and --allow-natives-syntax
to check whether an object already has fast properties.
$ npm install --save to-fast-properties
const toFastProperties = require('to-fast-properties');
const obj = {
foo: true,
bar: true
};
delete obj.foo;
// `obj` now has slow properties
toFastProperties(obj);
// `obj` now has fast properties
