String quotes

importance: 5

What is the output of the script?

let name = "Ilya";

alert( `hello ${1}` ); // ?

alert( `hello ${"name"}` ); // ?

alert( `hello ${name}` ); // ?

Backticks embed the expression inside ${...} into the string.

let name = "Ilya";

// the expression is a number 1
alert( `hello ${1}` ); // hello 1

// the expression is a string "name"
alert( `hello ${"name"}` ); // hello name

// the expression is a variable, embed it
alert( `hello ${name}` ); // hello Ilya
