How to Strip Duplicate Items from a JavaScript Array

stripDuplicates.js

// Duplicates: Bob, Aaron, Frank
const arrayWithDuplicates = ["Aaron", "Bob", "Chris", "Dave", "Edward", "Bob", "Aaron", "Frank", "George", "Frank", "Henry", "Bob", "Bob", "Aaron", "Aaron", "Frank"];

function stripDuplicates(arrayWithDuplicates) {
	let uniques = [];
	arrayWithDuplicates.forEach( (value, index) => {
		const indexWhereValueFirstAppears = arrayWithDuplicates.findIndex( (value_) => {
			return value_ === value;
		});
		if (index === indexWhereValueFirstAppears) {
			uniques.push(value);
		}
	});
	return uniques;
}

const arrayWithNoDuplicates = stripDuplicates(arrayWithDuplicates); 

arrayWithNoDuplicates.forEach( (unique) => {
	console.log("Unique: " + unique);
});
