The second parameter of insertAdjacentElement() should be a html object.
The trick below works :)


var htmlString = `

            
${obj.descripiton}
            

                
${obj.value}
                

                    
                
            
        
`
 var htmlObject = document.createElement('div');
 htmlObject.innerHTML=htmlString;
 document.querySelector(".income__list").insertAdjacentElement('beforeend', htmlObject);
