javascript - string templates not working - js -


i learning how template strings works es2015 somehow output not expected don't see did wrong.

can please give me hand?

function builduser(first, last){     let fullname = '${first} ${last}';      return { first, last, fullname }; }  let b = builduser("talyer", "willams"); console.log(b);

what object expected object returns

first: talyer last: willams fullname: ${first} ${last}

why getting ${first} ${last}? shouldn't talyer willams?

you need using backtick not single quote

let fullname = '${first} ${last}';

should 

let fullname = `${first} ${last}`;
