js firstelementchild code example

Example 1: first child element javascript

Both these will give you the first child node:

console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);

If you need the first child that is an element node then use:

console.log(parentElement.children[0]);

Example 2: javascript select first element

// example:
document.querySelector('.message')

// syntax:
// document.querySelector('.<class-name>')
