innertext.js

const NONTEXT_TAGS = [ 'SCRIPT', 'STYLE', 'IMAGE', 'VIDEO', 'AUDIO' ]

function isTextNode (node) {
	return NONTEXT_TAGS.indexOf(node.tagName) === -1
}

// Inner Text Less Code, But Slower
function innerText (node) {
	if (node.constructor.name === 'Text') {
		return node.textContent
	}

	return Array
		.from(node.childNodes)
		.filter(isTextNode)
		.map(innerText)
		.reduce((a, c) =>  a+c, '')
}

// Inner Text Faster, Recommended
function innerText (node) {
	if (node.constructor.name === 'Text') {
		return node.textContent
	}

	let text = ''
	const childNodes = node.childNodes

	for (let i = 0; i < childNodes.length; i++) {
		const childNode = childNodes[i]

		if (isTextNode(childNode)) {
			text += innerText(childNode)
		}
	}

	return text
}

// What's the problem with this?
// This seems the best and fastest
function innerText (node) {
	return node.textContent
}

// And lastly don't copy paste answers
// from Stack or anywhere else
// see the code, understand and then write
// your own code, otherwise, you get these
// callbacks which are 2010ish javascript
// Copy Paste works for consultancies lol
// You shouldn't do that when you're
// writing for your own
// You're cheating yourself




// Problems with Your Code
// It doesn't return the Whole Text
// It can only print
// while is useless!
