Element functions
isElement
<div id="my-element"></div>
import {isElement} from '@trinitymirrordigital/et-utilities/dist/elements';
const el = document.getElementById("my-element");
isElement(el); // returns trur
checkElements
<ul>
<li></li>
<li></li>
<li></li>
<li></li>
</ul>
import {checkElements} from '@trinitymirrordigital/et-utilities/dist/elements';
const elements = document.querySelectorAll("li");
checkElements(...elements); // returns true
parseBoolean
<div id="my-element" data-boolean="true"></div>
import {parseBoolean} from '@trinitymirrordigital/et-utilities/dist/elements';
const el = document.getElementById("my-element");
parseBoolean(el.dataset.boolean); // returns true
el.dataset.boolean = "false"
parseBoolean(el.dataset.boolean); // returns false
el.dataset.boolean = "foo"
parseBoolean(el.dataset.boolean); // returns null
parseNumber
<div id="my-element" data-num="123"></div>
import {parseBoolean} from '@trinitymirrordigital/et-utilities/dist/elements';

Currying
This allows you to curry a function. For more information on currying see https://mostly-adequate.gitbooks.io/mostly-adequate-guide/content/ch04.html
import curry from '@trinitymirrordigital/et-utilities/dist/curry';
const adder = (a, b) => a + b;
const add2 = curry(adder, 2); // return function
add2(3); // return 5
add2(5); // return 7
