@oticon/utilities

Chunk

Use Array.from() to create a new array, that fits the number of chunks that will be produced. Use Array.slice() to map each element of the new array to a chunk the length of size. If the original array can't be split evenly, the final chunk will contain the remaining elements.

chunk([1, 2, 3, 4, 5], 2);
// [[1, 2], [3, 4], 5]

countOccurrences

Use Array.reduce() to increment a counter each time you encounter the specific value inside the array.

countOccurrences([1, 1, 2, 1, 2, 3], 1);
// 3

Difference

Create a Set from b, then use Array.filter() on a to only keep values not contained in b.

difference([1, 2, 3], [1, 2]);
// [3]

Flatten

Use Array.reduce() to get all values inside the array and concat() to flatten them.

flatten([1, [2], 3, 4]);
// [1, 2, 3, 4]

Intersection

Create a Set from b, then use Array.filter() on a to only keep values contained in b.

intersection([1, 2, 3], [4, 3, 2]);
// [2, 3]

Shuffle

Use Array.sort() to reorder elements, using Math.random() in the comparator.

shuffle([1, 2, 3]);
// [2, 3, 1]

Similarity

Use Array.filter() to remove values that are not part of values, determined using includes().

similarity([1, 2, 3], [1, 2, 4]);
// [1, 2]

Union

Create a Set with all values from a and b, then convert values to an array.

union([1, 2, 3], [4, 3, 2]);
// [1, 2, 3, 4]

Unique

Use Set and the ...rest operator to discard all duplicated values.

unique([1, 2, 2, 3, 4, 4, 5]);
// [1, 2, 3, 4, 5]

Parameters

Use match() with an appropriate regular expression to get all key-value pairs, Array.reduce() to map and combine them into a single object. Pass location.search as the argument to apply to the current url.

parameters('https://oticon.com/?firstname=Sadi&lastname=Kaya');
// { firstname: "Sadi", lastname: "Kaya" }

Redirect

Use window.location.href or window.location.replace() to redirect to url. Pass a second argument to simulate a link click (default is true) or an HTTP redirect.

redirect('https://oticon.com', true);

Asset

Use process.env.NODE_ENV to return a string from an object.

asset({obj}, "mediapath", "mediaurl");
// if (prod) { mediapath } else { mediaurl }

Log (Sentry.io)

If you're using React 16 or above, Error Boundaries are an important tool for defining the behavior of your application in the face of errors. Be sure to send errors they catch to Sentry using Raven.captureException.

log(ex, extra);

Parse

parse(xml);
// xml -> js

XMLParser

XMLParser(xml);
// xml -> js

Preload Images

preloadImages(arr);

UUID

Use the crypto API to generate a UUID, compliant with RFC4122 version 4.

uuid();
// "7982fcfe-5721-4632-bede-6000885be57d"
