What does the program print?

JavaScript

const n = 2;

console.log(`a${n}b`, "a${n}b");

a2b a${n}b

Expecting a2b a2b: ${} inserts a value only inside backticks; in ordinary double quotes it is plain text and prints as written.
Expecting SyntaxError for ${ inside double quotes: any characters may sit inside quotes, so the string is valid and keeps them as they are.

How would you build the same a2b string with + instead of a template literal?
What does a template literal print when it spans two lines of code?
