 //problem: we are trying to use the variable "cityOfBirth" before it has been declared and assigned a value. In JavaScript, variables declared with "const" or "let"  cannot be accessed before they are declared. To fix this error, we need to declare and assign a value to "cityOfBirth" before we try to use it. So we would move the line "const cityOfBirth = "Bolton";" above the console.log statement.
