Exploring Angular 6: Understanding the Reflect API within the polyfills.ts File

The file polyfills.ts includes a commented out line that states:

/** IE10 and IE11 requires the following for the Reflect API. */
// import 'core-js/es6/reflect';

Can you explain what the 'Reflect API' is? Why is it needed for Internet Explorer (IE) and is this import statement essential when running an Angular application in IE? Interestingly, I couldn't find much information on Google or StackOverflow regarding this topic.

Answer №1

The ES6 Reflect API introduces the Reflect object, which allows users to execute methods, create objects, access and modify prototypes, and manipulate properties. Reflect serves as a built-in object that facilitates interceptable JavaScript operations, offering methods similar to those found in proxy handlers. For more information, please refer to the Reflect documentation and the ES6 Reflect API Tutorial.

According to the Browser compatibility Section, Internet Explorer does not support Reflect. However, by using polyfills, it is possible to enable the use of Reflect in the IE browser.
