Different ways to log messages in Nodejs

How many ways do you know ?
According to my little research, there are 3 different ways you can log messages in π—‘π—Όπ—±π—²π—·π˜€.

1- π—°π—Όπ—»π˜€π—Όπ—Ήπ—².𝗹𝗼𝗴: We all know this one and have used it extensively in Javascript. What people don't know that under the hood it actually uses π—½π—Ώπ—Όπ—°π—²π˜€π˜€.π˜€π˜π—±π—Όπ˜‚π˜.π˜„π—Ώπ—Άπ˜π—² with a line break.

2- π—½π—Ώπ—Όπ—°π—²π˜€π˜€.π˜€π˜π—±π—Όπ˜‚π˜.π˜„π—Ώπ—Άπ˜π—²: Unlike the previous one, this outputs messages on the same line; so you're going to need to manually add like breaks.

3- π—³π˜€.π˜„π—Ώπ—Άπ˜π—²π—¦π˜†π—»π—°: Also requires manual line breaks. Writes to π—½π—Ώπ—Όπ—°π—²π˜€π˜€.π˜€π˜π—±π—Όπ˜‚π˜.π˜„π—Ώπ—Άπ˜π—² like π—°π—Όπ—»π˜€π—Όπ—Ήπ—².𝗹𝗼𝗴. This method though is a little unique. It takes an integer as the first argument, something called a 𝗳𝗢𝗹𝗲 π—±π—²π—°π—Ώπ˜†π—½π˜π—Όπ—Ώ. To make it write to the π˜€π˜π—±π—Όπ˜‚π˜, you have to set it to 1. I'll talk about it in my next post.
