Hi Ricky,

First, declare a variable named after the function (my personal preference is to store functions inside variables). The variable, in this case, contains the function (block of code designed to perform a particular task).

Then, set greet to the function. The function can list parameters, if you wish. You can leave out the parenthesis if your function has a single parameter. Parameters are arguments to be imported into the function, when called.

Finally, type the => followed by curly braces; within goes the function's content:

var greet = val => {
  return `Hi, ${val}!`;
}

Test by printing to the console. Call the function by the variable's name. Replace val by the argument you want to pass into the function.

console.log( greet(`Ricky`) );
