CodePudding user response：

You have to use backticks instead of normal quotationmarks.

const firstName = "Mohamed";
const lastName = "Eldamaty";
const sentence = `Hello ${firstName}` ;
console.log(sentence);

CodePudding user response：

You are not using template strings, so absolute value is being logged. Do this:

const sentence = `Hello ${firstName}` ;

Use backticks (`) to use template strings.
