Combining strings via Concatenation

Below role, create a new variable named msg that combines the firstName, lastName and role variables to create a string like "Carlos Salgado: developer".

  1. let firstName = 'Carlos';
  2. let lastName = 'Salgado';
  3. let role = 'developer';

My answer

  1. let firstName = "Carlos";
  2. let lastName = "Salgado”;
  3. let role = 'developer';
  4. let msg = 'firstName' + 'lastName’ + 'role’;

I am getting a Bummer. Please help.

Hi Chinonso Umeanoikwa

You are close, but you need to make some adjustments. Right now you are just saving the string firstNamelastNamerole to the msg variable.

You need to remove the quotes around the variable names in order to get the variable’s value. Or you can use template literals with backticks to create the correct string with the variable names. If using backticks, remember to use interpolation to add the variable values into the string.

Finally you need to make sure you have the format required for the challenge, in this case you are missing some white spaces between first and last name and you are also missing an : and a white space after the last name.

Something like this:

let msg = firstName +   + lastName + :  + role;

Or with backticks

let msg = `${firstName} ${lastName}: ${role}`;
