What is the reason for instanceof Map returning false?

Utilizing the Draft.js plugin called Mention.

When accessing

editorState.content.entityMap.mention
, I am able to retrieve the value by:

mention.get('address')

However, when I attempt to verify if it is a Map using:

console.log('mention', mention);
console.log('mention instanceof Map', mention instanceof Map);

The result returned is false. Although the console indicates that mention is indeed a Map.

Answer №1

When referencing Map in JavaScript, it can be confusing as there are different implementations. After examining the source code of Draft.js (line 2), I discovered that they utilize a distinct map structure compared to the one found in this library. It's important to note that these two maps should not be directly compared as they serve different purposes.
