Difference between console.log and process.stdout.write in NodeJS

Both the methods – console.log and process.stdout.write have a basic definition to write or print the statements on the console. But, there is a slight difference in the way they execute these tasks. Internally, console.log implements process.stdout.write which itself is a buffer stream that will be used to directly print statements on your console.

process.stdout.write

Example 1

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

Output

HelloWorld!!!
console.log

Example 2

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

Output

Hello
World
!!!
