How is the 'use strict' statement interpreted in Node.js?

0 votes
I have started to explore the Node.js and wrote many demo web application, to understand the flow of Node.js, Express.js, jade, etc..

But one thing I came across recently, is the statement "use strict" as the first line inside every function and every .js file.

How exactly is it is interpreted by Node.js?

Hello @kartik,

"use strict";

Basically it enables the strict mode.

Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.

Hope it helps!!
Thank you!!
