How to include variable when creating button with Javascript?

Question

I'm creating buttons dynamically from a javascript for loop by adding this code.

var container = document.getElementById('myList');
var new_element = document.createElement('li');
new_element.innerHTML = '<button type="button" id="">label</button>';

I need to add elements from an array to both the buttons id and label. Like this for example;

arrMarkers[i].title

How can I enclose these array values in the string that creates the button?

whats the issue? its a usual concate '<button type="button" id="'+arrMarkers[i].title+'">label</button>'; — Rab Khan

newElement.innerHTML = '<button type="button" id="' + arrMarkers[i].id + '">' + arrMarkers[i].title + '</button>';

As I understood, you are looking for string concatenation:

new_element.innerHTML = '<button type="button" id="' + arrMarkers[i].id + '">' + arrMarkers[i].title + '</button>';
