what is the difference between " and ` in JS?

Question

this is quite an easy question but is not obvious to me.

What is the difference between this:

function fesElsDeures(subject){ 
console.log(`just started doing my ${subject} `);
}

and this:

function fesElsDeures(subject){ 
console.log("just started doing my ${subject} ");
}

It seems that in the second option, my console does not recognise the subject as a different value.

Thanks!

Answer 1

Double quotes or single qoutes are just indicating string. But in first example there are not single quotes. It's a back-tick (` `) and it allows you to use embedded expression( in this case 'subject' parameter of your function).

Answer 2

Don't to be confuse with ' (Single quote) with ` (back-tick).

• " is Double quotes,
• ' is single quotes
• ` is back-tick.

when you use back-tick, it allows you write multi line texts. Template literals
