# Uint8Arrays

Some utility functions to make dealing with `Uint8Array`s more pleasant.

## API

### compare(a, b)

Compare two `Uint8Arrays`

#### Example

``````import { compare } from 'uint8arrays/compare'

const arrays = [
Uint8Array.from([3, 4, 5]),
Uint8Array.from([0, 1, 2])
]

const sorted = arrays.sort(compare)

console.info(sorted)
// [
//    Uint8Array[0, 1, 2]
//    Uint8Array[3, 4, 5]
// ]
``````

### concat(arrays, [length])

Concatenate one or more array-likes and return a `Uint8Array` with their contents.

If you know the length of the arrays, pass it as a second parameter, otherwise it will be calculated by traversing the list of arrays.

#### Example

``````import { concat } from 'uint8arrays/concat'

const arrays = [
Uint8Array.from([0, 1, 2]),
Uint8Array.from([3, 4, 5])
]

const all = concat(arrays, 6)

console.info(all)
// Uint8Array[0, 1, 2, 3, 4, 5]
``````

### equals(a, b)

Returns true if the two arrays are the same array or if they have the same length and contents.

#### Example

``````import { equals } from 'uint8arrays/equals'

const a = Uint8Array.from([0, 1, 2])
const b = Uint8Array.from([3, 4, 5])
const c = Uint8Array.from([0, 1, 2])

console.info(equals(a, b)) // false
console.info(equals(a, c)) // true
console.info(equals(a, a)) // true
``````

### fromString(string, encoding = 'utf8')

Returns a new `Uint8Array` created from the passed string and interpreted as the passed encoding.

Supports `utf8` and any of the multibase encodings as implemented by the multiformats module.

#### Example

``````import { fromString } from 'uint8arrays/from-string'

console.info(fromString('hello world')) // Uint8Array[104, 101 ...
console.info(fromString('00010203aabbcc', 'base16')) // Uint8Array[0, 1 ...
console.info(fromString('AAECA6q7zA', 'base64')) // Uint8Array[0, 1 ...
console.info(fromString('01234', 'ascii')) // Uint8Array[48, 49 ...
``````

### toString(array, encoding = 'utf8')

Returns a string created from the passed `Uint8Array` in the passed encoding.

Supports `utf8` and any of the multibase encodings as implemented by the multiformats module.

#### Example

``````import { toString } from 'uint8arrays/to-string'

console.info(toString(Uint8Array.from([104, 101...]))) // 'hello world'
console.info(toString(Uint8Array.from([0, 1, 2...]), 'base16')) // '00010203aabbcc'
console.info(toString(Uint8Array.from([0, 1, 2...]), 'base64')) // 'AAECA6q7zA'
console.info(toString(Uint8Array.from([48, 49, 50...]), 'ascii')) // '01234'
``````

### xor(a, b)

Returns a `Uint8Array` containing `a` and `b` xored together.

#### Example

``````import { xor } from 'uint8arrays/xor'

console.info(xor(Uint8Array.from([1, 0]), Uint8Array.from([0, 1]))) // Uint8Array[1, 1]
``````
