Implementation of the Print method

This is no difficulty, just console.log change the name of the thing, a line of code can be solved.

var print = Console.log

implementation of Read_line method

As we Node.js all know, it is an asynchronous language, so it is readline also an asynchronous operation, according to the node. JS Chinese documentation, readline this is done:

Const ReadLine = require (' readline '= readline.createinterface ({  Input:process.stdin,  output: Process.stdout}); Rl.question (' What do you think of the node. JS Chinese web? ', (answer) = {  //  to process the answer   console.log (' Thank you for your feedback: ${answer} ');  Rl.close ();});

or it is done in the following way:

Rl.on (' line ', (input) = {  Console.log (' Received: ${input} ');});

installation readline-sync , Node.js environment, I will not introduce a lot of the big boys are very clear. Yes, if it cli is useful to write a tool, but now the needs are different, we need to copy to the answer box can be directly run code, now the artifact should appear.

NPM Install Readline-sync

Despair is still GitHub reliable, only two steps to achieve the read_line method:

var __readline = require (' Readline-sync '})var read_line = __ Readline.prompt

Before writing, copy the following code to the previous
