Test name	Executions per second
uint32 array random get	1980623.4 Ops/sec
simple array random get	1974719.0 Ops/sec

Script Preparation code:

uint32Array = new Uint32Array(1e5);
simpleArray = new Array(1e5);
temp = 0;
for(let i = 0; i < 1e5; i++) {
  uint32Array[i] = simpleArray[i] = Math.floor(Math.random() * (2 << 32));
}

Tests:

uint32 array random get
temp = uint32Array[Math.floor(Math.random() * 1e5)];
simple array random get
temp = simpleArray[Math.floor(Math.random() * 1e5)];
