Error as '`' (backquotes) not allowed in javascript (ecma5)

Question

var now = new Date();

var year = now.getUTCFullYear();
var month = now.getUTCMonth() + 1;
var day = now.getUTCDate();
var hours = now.getUTCHours();
var minutes = now.getUTCMinutes();
var seconds = now.getUTCSeconds();
var milliseconds = now.getUTCMilliseconds();
var test = `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;
console.log(test);

Are backquotes not allowed in javascript (`) ? I am trying in ecma5 but getting error as mentioned above.

And also, can we match regular expression for above mentioned date-time format ?

WHAT is giving you that error? It is part of ECMAScript 6, not 5. — epascarello, Jun 08 '23 at 15:25
To answer your question, yes template literals ("backquotes") are part of ES2015/ES6. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals#browser_compatibility — Patrick, Jun 08 '23 at 15:25

Right now, the lastest version of JS is EcmaScript6, and many references online use EcmaScript13 specs.

Backticks are not allowed in Ecmascript 5, they were added to serve easier access to multi-lined strings in EcmaScript6.

You can use the + sign:

let a = year+'-'+month+'-'+day+' '+hours+':'+minutes+':'+seconds;

"*the lastest version of JS is EcmaScript6*" - nope. We're at [EcmaScript 13.0](https://262.ecma-international.org/13.0/) right now, and getting a new version every year. – Bergi Jun 08 '23 at 15:35
Sorry, You're right we're way over ES6 – Hermanboxcar Jun 08 '23 at 15:40
thanks for mentioning about these version changes. – Learner Jun 08 '23 at 16:01
