JavaScript

// Hunting flags in the Document
//
// Using only the built-in DOM methods
// Find the three elements that have the text "FLAG" inside them
// and move them (the element) into the div with id of #bucket
//
// Hint: You can use
//     document.getElementById
//     document.getElementsByTagName
//     document.getElementsByClassName
//     document.querySelector
//     document.querySlectorAll
// and all the parent, child and sibling selectors

// 1) get FLAG 1
var flag1 = document.getElementById('container').childNodes

for (var i = 0; i < flag1.length; i++) {
	console.log(flag1[i]);
}

// 2) get FLAG 2


// 3) get FLAG 3

// bonus: write a function to crawl the entire document and search for the "FLAG" text, and do the job for you.
