Difference between process.stdout.write and console.log in Node.js

Both process.stdout.write and console.log in NodeJS have basic functionality to display messages on the console. Basically console.log implement process.stdout.write while process.stdout.write is a buffer/stream that will directly output in our console.

Difference between process.stdout.write and console.log in Node.js are:

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.

Example: Below example is to show to use of process.stdout.write

Javascript

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

Output:

HelloWorld!!!

Example: Below example is to show to use of console.log

Javascript

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

Output:

Hello
World
!!!
