Variable is not replaced by its value

am kind of novice to nodeJS and javascript, while trying to print a variable value, the variable isn't getting replaced by its value.

var a="World";
console.log("Hello ${a}");

am getting "Hello ${a}" instead of "Hello World"

you can use this , you need to put assigned variable(a) out of string "" or else it will considered as a string

   var a="World";
console.log("Hello",a);

If you are using ES6 you can use template literals with placeholders (which you are trying to do it seems):

var a="World";
console.log(`Hello ${a}`);

Other option is the traditional way, concatenating strings with the + operator:

var a="World";
console.log("Hello " + a);

You need to use `` instead of "" . For more see Interpolation in Javascript

var a="World";
console.log(`Hello ${a}`);
