Placeholders

Enough about numbers, let's check out what we can do with strings !

Strings `${placeholders}`

The first one are placeholders for using values inside our strings, they have there own syntax: ${}.

Example

console.log(`5 + 10 = ${5 + 10} = 15`) // -> 5 + 10 = 15 = 15

Note that it only works using: the ` backtick, not the " or ' quotes.

// here, with the use of quotes instead of backticks, the placeholder is not evaluated and we see it as text:
console.log('5 + 10 = ${5 + 10} = 15') // -> 5 + 10 = ${5 + 10} = 15

Instructions

We will provide a variable name and age. They will be pre-declared by us.

Declare a presentation variable of the string:

Hello, my name is name and I'm age years old

But use placeholders to build the string you will put inside presentation.
Put the values of the provided variables age and name inside those placeholders.
