<!--your preparation HTML code goes here-->

Script Preparation code:

const createSubArray = () => Array(100).fill(Math.random());

var src = Array(100).fill(createSubArray())
var dest = Array(100).fill(createSubArray())

Tests:

i,j
for(let i=0; i<100; i++){ for(let j=0; j<100; j++){ dest[i][j] = src[i][j]; } }
j,i
for(let i=0; i<100; i++){ for(let j=0; j<100; j++){ dest[j][i] = src[j][i]; // 添え字の順番が逆 } }
i,j pre-optimized
for(let i=0; i<100; i++){ const dest_i = dest[i] const src_i = src[i] for(let j=0; j<100; j++){ dest_i[j] = src_i[j]; } }
