Are you still using console.log for all your JavaScript needs in 2024?
It's time to upgrade.
If you console.log() the console object, the following would be the output -
Your first time seeing this many functions inside the console object, right?
One of the biggest problems with using just console.log is that it's not very informative on its own.
It just outputs the value of whatever you pass to it without any context or additional information.
In this post, let us explore some of them, which can actually replace the need to use console.log().
[not really, this classic function is just way, way better than others]
1️⃣ console.error();
Outputs an error message to the console.
console.error("ERROR");
2️⃣ console.warn();
Outputs a warning message to the console.
console.warn("WARNING");
3️⃣console.table();
Outputs a warning message to the console.
console.table([{ name: 'John', age: 30 }, { name: 'Jane', age: 25 }]);
4️⃣ console.assert();
Logs a message to the console only if an expression evaluates to false.
console.assert(2 + 2 === 5, "Error: Math is broken!");
console.assert(2 + 2 === 4, "Error: Math is broken!");
5️⃣ console.info();
Outputs an informational message to the console.
To be honest, this is a console.log() in disguise.
console.info("Informational message");
BONUS: 6️⃣ console.log( {} );
Try to put an object inside the console.log() parameter. It will make the output more readable.
Just see the difference!

In 2024, don’t just use console.log - there are many more powerful and valuable functions available.
