Functional
const arr1 = new Array(100).fill().map(()=>new Array(100).fill().map(()=>100));
New array
const arr3 = new Array(100); for (let i=0;i<100;i++) { arr3[i] = new Array(100); for (let j=0;j<100;j++) { arr3[i][j] = 100; } }
Uint8 array
const arr4 = new Uint8Array(100); for (let i=0;i<100;i++) { arr4[i] = new Array(100); for (let j=0;j<100;j++) { arr4[i][j] = 100; } }
Push destructured row
const arr5 = []; for (let i=0;i<100;i++) { const row = []; for (let j=0;j<100;j++) { row.push(100); } arr5.push([...row]); }
Push row (closure)
const arr6 = []; for (let i=0;i<100;i++) { const row = []; for (let j=0;j<100;j++) { row.push(100); } arr6.push(row); }
