getElementsByClassName()[ ]

Question

if we write "getElementsByClassName()[ 1]";we select only second element but if I want to select all elements what must I write ?

Answer 1

document.getElementsByClassName("example") is the pointer of the Node.
To access or update all the class elements, you still need to iterate the arrays, eg.

var items = document.getElementsByClassName("item")

Array.prototype.forEach.call(items, (el,i)=>{el.innerText = "Item "+ i})

Answer 2

just use it without specifying any index between square brackets:
document.getElementsByClassName("example");
