<!--:)<:-->

Script Preparation code:

const SIZE = 10000;

const float64 = new Float64Array(SIZE);
const float32 = new Float32Array(SIZE);
const float16 = new Float16Array(SIZE);

for (let i = 0; i < SIZE; i++) {
    float64[i] = 1.234;
    float32[i] = 1.234;
    float16[i] = 1.234;
}

Tests:

Float64Array Read
let sum = 0; for (let i = 0; i < SIZE; i++) { sum += float64[i]; } return sum;
Float32Array Read
let sum = 0; for (let i = 0; i < SIZE; i++) { sum += float32[i]; } return sum;
Float16Array Read
let sum = 0; for (let i = 0; i < SIZE; i++) { sum += float16[i]; } return sum;
Float64Array Write
for (let i = 0; i < SIZE; i++) { float64[i] = 1.235; }
Float32Array Write
for (let i = 0; i < SIZE; i++) { float32[i] = 1.235; }
Float16Array Write
for (let i = 0; i < SIZE; i++) { float16[i] = 1.235; }
