Node.js check for ES6 support

ode.js is developing very fast, and its support for es6 features is becoming more and more conscientious. However, there are many versions of node.js, and each version has different support for es6. In order to clearly understand how each version supports es6 features To support, there needs to be a tool that can provide clearer support instructions, and can even provide support for a certain feature by calling it in the program, and help the program selectively use es6 features.

es-checker provides relatively easy-to-use related functions. It can detect the current node and provide feature support instructions. It can also provide methods in the program to detect whether a certain feature is supported.

Installation and detection

The current node version is v6.9.4.
