How to call function? Combinding template literal and arrow functions

Hello

How do i make my code into a function that i can call?

I used template literals and arrow functions in this code.

https://teamtreehouse.com/library/getting-started-with-es2015-2

function:

let myName = "Kevin"
const lastName= "Ohlsson"


const message = () => {
    `
        ${myName} is ${lastName}
    `
    console.log(message)
}

message()

original:

scripts.js
let myName = "Kevin"
const lastName = "Ohlsson"

const message = `${myName} is ${lastName}`;

alert(message)

You were close, but you need to assign your string to a variable, and log that variable instead of the function itself:

const message = () => {
    const msg = `
        ${myName} is ${lastName}
`;
    console.log(msg);
};

Thank you Steven!

I guess i tried to log the function itself and the string was lost in memory because it was not temprarily assigned to any variable.

Iยดll practise more :)

A translation of my first code snippet to a "normal" function would be:

messageOne() {
    `${myName} is ${myAge}`
    console.log(messageOne)
}

messageOne()

Here is the code again, but now using your example.

function messageTwo() {
    const msg = `${myName} is ${myAge}`
    console.log(msg)
}

messageTwo()

Makes it easy to see the misstake

Cheers!

And if I may suggest, also practice the good habit of ending statements with semicolons. :wink:

Good eye! I keep missing them! I need to come up with a mantra about semicolons so i remember them.

Each javascript stolon gets swollen and ends with a semi-colon;
