Insert array of elements into the DOM? [duplicate]

Answer 1

You may simply use .append() to append multiple DOM nodes all at once as follows;

var divs = Array.from({length:10}) // lets make an array of 10 divs
                .map(function(_,i){
                       var el = document.createElement('div');
                       el.textContent = `I am div # ${i}`;
                       return el;
                     });
document.body.append(...divs);
