Script Preparation code:

var array = new Array(100000).fill(0).map(_x => 0);
var typedArray = new Uint32Array(100000).fill(0);

Tests:

Array write
for (let i=0; i<array.length; i++) { array[i] = array[i] + 1; }
TypedArray write
for (let i=0; i<typedArray.length; i++) { typedArray[i] = typedArray[i] + 1; }
