What is vlq?

The vlq npm package is used for encoding and decoding variable-length quantities (VLQs). VLQ is a universal code that uses an arbitrary number of binary octets (eight-bit bytes) to represent an arbitrarily large integer. It is used in various data serialization and compression contexts, including source map generation for web development.

What are vlq's main functionalities?

Encoding integers to VLQ

This feature allows you to encode integers into VLQ strings. The `encode` function takes an integer and returns a string representing the encoded VLQ.

"use strict"; const vlq = require('vlq'); const encoded = vlq.encode(123); console.log(encoded); // Output: '2H'

Decoding VLQ strings to integers

This feature allows you to decode VLQ strings back into integers. The `decode` function takes a VLQ-encoded string and returns an array of integers.

"use strict"; const vlq = require('vlq'); const decoded = vlq.decode('2H'); console.log(decoded); // Output: [123]
