How can i concatenate variable between two strings in JQuery

Question

I am trying to concatenate var value between two strings to get my code work, but I'm getting error of unexpected token or invalid string while trying different ways: to concatenate using concat function or with dot between string.

Below the code:

var hash = window.location.hash;
var href = 'a[href="'.concat(hash) '"]';
alert(href);
if(hash != "") {
 jQuery(".tab-content-panel").hide();
 var id = jQuery(hash).show();
 jQuery('.tabs-custom-nav li a').removeClass('current');
//jQuery('.tabs-custom-nav li a[href="'.hash "]').addClass('current');

//alert(id);
  }
 //alert(hash);

You don't need to use concat: in fact, you can't use it, since it is an Array prototype. You can either use + to concatenate strings:

var href = 'a[href="' + hash + '"]';

Or use ES6 template literals:

var href = `a[href="${hash}"]`;

Why not use simple + to concat strings? But please be aware of security risks you may run into. If this does what you expect, fine. But keep security issues in mind.

var hash = window.location.hash;
var href = 'a[href="'+hash+'"]';
alert(href);
