Script Preparation code:
var iterations = 10000;
Tests:
fill then edit with for
const array = new Uint8Array(iterations).fill(0); for(let i=0;i<iterations;i+=2) array[i]=1;
map
new Uint8Array(iterations).map((_, i) => i%2?0:1);
for loop
const array = new Uint8Array(iterations); for(let i=0;i<iterations;i++) array[i]=i%2?0:1;
