The editor will share with you how JavaScript uses instanceof. I hope you will get something after reading this article. Let's discuss it together.

Instanceof

The principle is to recursively traverse the prototype chain of the right parameter, comparing it with the left parameter each time, returning false when traversing to the end of the prototype chain, and returning true if found.

What are the characteristics of JavaScript? 1. Js belongs to an explanatory scripting language. 2. With the support of most browsers, js can run on multiple platforms and has cross-platform characteristics. 3. Js is a weakly typed scripting language that does not make strict requirements on the data types used. It is able to type conversion, simple and easy to use. 4. Js language is highly secure, and it can only browse information or interact dynamically through the browser, so as to effectively prevent the loss of data. 5, object-based scripting language, js can not only create objects, but also use existing objects.
