Trying to have console log show the initials of the first and last name when using arrow functions in javascript.
const getInitials = (firstName, lastName) => {
firstName + lastName;
}
console.log(getInitials("Charlie", "Brown"));

You have to specify return inside the curly brackets. You can use charAt() to get the initials:
const getInitials = (firstName,lastName) => { return firstName.charAt(0) + lastName.charAt(0); }
console.log(getInitials("Charlie", "Brown"));OR: You do not need the return if remove the curly brackets:
const getInitials = (firstName,lastName) => firstName.charAt(0) + lastName.charAt(0);
console.log(getInitials("Charlie", "Brown"));

(They're also looking for initials rather than entire strings)
Get first chars from names.
const getInitials = (firstName, lastName) => `${firstName[0]}${lastName[0]}`
console.log(getInitials("Charlie", "Brown"));

You're not returning the initials, you're returning the whole name. Use [0] to get the first character of a string.
In an arrow function, don't put the expression in {} if you just want to return it as a result.
const getInitials = (firstName, lastName) => firstName[0] + lastName[0];
console.log(getInitials("Charlie", "Brown"));Comments
When you give an arrow function a code block ({}), you need to explicitly define the return statement. In your example, you don't need a code block since you're only wanting to return a single value. So, you can remove the code block, and instead place the return value to the right of the arrow =>.
In order to get the first characters in your strings, you can use bracket notation ([0]) to index the string, .charAt(0), or even destructuring like so:
const getInitials = ([f],[s]) => f + s;
console.log(getInitials("Charlie", "Brown"));
