Uncaught TypeError: Failed to execute 'insertAdjacentElement' on 'Element': parameter 2 is not of type 'Element'
The second parameter of insertAdjacentElement() should be a html object.
The trick below works :)
var htmlString = `<div class="item clearfix" id="income-${obj.id}">
<div class="item__description">${obj.descripiton}</div>
<div class="right clearfix">
<div class="item__value">${obj.value}</div>
<div class="item__delete">
<button class="item__delete--btn"><i class="ion-ios-close-outline"></i></button>
</div>
</div>
</div>`
var htmlObject = document.createElement('div');
htmlObject.innerHTML=htmlString;
document.querySelector(".income__list").insertAdjacentElement('beforeend', htmlObject);
