NodeJS中process.stdout.write和console.log的区别

NodeJS中的 process.stdout.write和 console.log 都具有在控制台上显示消息的基本功能。基本上console.log实现process.stdout.write而process.stdout.write是一个缓冲区/流，将直接在我们的控制台中输出。

Node.js 中 process.stdout.write 和 console.log 的区别是：

Sl no.	process.std.out	console.log
1	It continuously prints the information as the data being retrieved and doesn’t add a new line.	It prints the information that was obtained at the point of retrieval and adds a new line.
2	Using process.stdout for a variable that shows an object.	Using console.log for a variable shows a lot of unreadable characters.
3	It only takes strings as arguments. Any other data type passed as a parameter will throw a TypeError.	It takes any JavaScript data type.
4	If we don’t put the break line at the end we will get a weird character after our string.	We don’t need the break line here because it was already formatted and also that weird character did disappear
5	It can be useful for printing patterns as it does not add a new line.	It is used when we want our result to be printed in a new line.
6	We can not write more than one string. For example: process.stdout.write("Hello","World"); Output: This will give a type error.	We can write more than one string. For example: console.log("Hello", "World"); Output: This will print Hello World in the console.
7	We can not make associations. For example: process.stdout.write("Hello %s", "All"); Output: This will give a type error.	We can make associations. For example: console.log("Hello %s", "All"); Output: This will print Hello All in the console.

示例：下面的示例展示了process.stdout.write 的使用

Javascript

    // For process.std.out 
    process.stdout.write("Hello");
    process.stdout.write("World");
    process.stdout.write("!!!");

输出：

HelloWorld!!!

例子：下面的例子是展示console.log的使用

Javascript

    // For console.log 
    console.log("Hello");
    console.log("World");
    console.log("!!!");

输出：

Hello
World
!!!
