Function encodeBytes has a Cognitive Complexity of 20 (exceeds 5 allowed). Consider refactoring.
Open

export const encodeBytes = (src: Uint8Array) => {
    const freq = new Uint32Array(FREQ).fill(1);
    const out = new BitOutputStream(Math.max(src.length >> 1, 1));
    const len = src.length;
    let total = FREQ;

Cognitive Complexity

Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

A method's cognitive complexity is based on a few simple rules:

  • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
  • Code is considered more complex for each "break in the linear flow of the code"
  • Code is considered more complex when "flow breaking structures are nested"

Function decodeBytes has a Cognitive Complexity of 16 (exceeds 5 allowed). Consider refactoring.
Open

export const decodeBytes = (src: Uint8Array) => {
    const freq = new Uint32Array(FREQ).fill(1);
    const input = new BitInputStream(src);
    const nbits = input.length;
    const out = [];
