so, we have normal functions:

//regular function
function aNameForFunction(aparametertogive) {
  // run some code here.  
}; 

// arrow functions (also known as fat arrow syntax) 
const aNameForFunction = (parameter, moreparameter, ...) => {
  // run some code.  
}; 

Now... there are a few things we can do with arrow functions that are really powerful. If we have only 1 parameter, we don't need parentheses, like this:

const aFunction = aparameter => {
  // run some code.  
}

And finally, we have another thing we can do... if we only have 1 liners.. we can ignore the brackets too!

const aFunction = aparameter => console.log('This is a one liner implicit returned console log!'); 

// a more powerful example:  
const anArray = [1, 2, 3, 4, 5]; 
const aGoodFunction = anArray => anArray.forEach(itemInTheArray => console.log(itemInTheArray));
