4,559 PointsHow 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 ${lastName}
`
console.log(message)
}
message()
original:
let myName = "Kevin"
const lastName = "Ohlsson"
const message = `${myName} is ${lastName}`;
alert(message)

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

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:
Here is the code again, but now using your example.
Makes it easy to see the misstake
