If you started learning Javascript then I can bet you that the first line of code you wrote was
console.log("Hello World!");
We all use console.log() a lot in our Javascript code for debugging and sometimes we write it just for fun😉.
Usually, we use console.log() like this:
// old way
console.log("Hello World!"); //Hello World
console.log(4+4); //8
We can optimize a little bit by using the arrow function like this:
// new and efficient method
const l=(args)=>{
console.log(args);
}
l("hello World!"); ////Hello World
l(4+4); //8
Writing the function one's you can now just use l to make things work.
WHY to do this
- It makes your code DRY
- Gives your code aesthetics and makes it look neat.
- Saves a little bit of time.
