Saturday #javascript fun -- a little helper function for closest() that handles the possibility of the input being a text node:

const getClosest = (node, query) => {  
 if(!node) {  
 return null;  
 }  
 while(node.nodeType !== Node.ELEMENT_NODE) {  
 if(!(node = node.parentNode)) {  
 return null;  
 }  
 }  
 return node.closest(query);  
};
