Tests:
JSON serialization
const arr = Array.from({ length: 5000 }).map(() => Math.random()); const serialized = JSON.stringify(arr); const deserialized = JSON.parse(serialized); const serializedAgain = JSON.stringify(deserialized);
ArrayBuffer serialization
const arr = Array.from({ length: 5000 }).map(() => Math.random()); const buffer = new ArrayBuffer(arr.length * 4); const view = new DataView(buffer); for (let i = 0; i<buffer.byteLength; i+=4){ view.setFloat32(arr[i]); } const view2 = new DataView(buffer);
