Script Preparation code:

var sample_arr = new Array()
for (const x of Array(5).keys()) {
    window.sample_arr = {
        x,
        y: x + 1
    }
}
console.log(window.sample_arr)

Single Loop
// s1 = sample_arr.map(x => console.log(x.x, x.y)) for (const x of sample_arr) { console.log(x.x, x.y) }
2 seq Loops
//s2 = sample_arr.map(x => console.log(x.x)) //s3 = sample_arr.map(x => console.log(x.y)) for (const x of sample_arr) { console.log(x.x) } for (const x of sample_arr) { console.log(x.y) }
