we need to define message with const message = greeting + myName;
|
|
||
| let myName = name.trim(); | ||
| let nameLength = myName.length; | ||
| message = |

Hey Natalie. Not your fault since the examples used this, but going forwards always use let or const when defining variables. var is not used anymore :)
In some places you were able to define a variable like message = a + b this is because your IDE is not using javascript in strict mode. I'll talk about this in class more, but have a read online about this
Another way, which i prefer, to concate strings is a string literal have a look below.
Both messages will output the same
const name = 'John Doe'
const age = '30'
const job = 'Web Developer'
const message = `My name is ${name} and I am ${age} years old. I am a ${job}`
const message1 = 'My name is ' + name + ' and I am ' + age + ' years old. I am a ' + job
// My name is John Doe and I am 30 years old. I am a Web Developer
If you need more clarity let me know
| var numberOfStudents = 15; | ||
| var numberOfMentors = 8; | ||
| let total = numberOfMentors + numberOfStudents; | ||
| console.log('Total number of students and mentors:' + ' ' + total); No newline at end of file |

You can add a space at the end of the string here rather than having + ' '
console.log('Total number of students and mentors: ' + total);
| total = a ++ b; | ||
|
|
||
| return "The total is total"; | ||
| total = a + b; |

thanks very much for the comments, @Hamisakim . This is noted |
