How do I sort array so that this output
[ [ '6.9', '14.5' ], [ '22.2', '28.9' ] ]
is sorted primarily with x value so 6.9 and 22.5 in the above example and secondarily with y axis, 14.5 and 28.9 in the above example.
this is my code currently to get the output.
const mySet = uniqueArray4(x_y_total);
mySet.forEach(element => {
let sumx = 0, sumy = 0;
for(let i = 0; i < element.length; i++) {
sumx += element[i][0]/element.length;
sumy += element[i][1]/element.length;
}
answer.push([sumy.toFixed(1), sumx.toFixed(1)]);
});
answer.forEach(element => {
finalanswer.push(element);
})
Quite new to js, I searched through google but it's been quite difficult as to how should I implement this.
You can sort based on the 1st entry, and then on the 2nd entry, something like:
// Sorting on 1st param
answer.sort((a,b) => a[0] - b[0]);
// Sorting on 2nd param given then 1st param is sorted, if not, return 0
answer.sort((a,b) => a[0] < b[0] ? a[1] - b[1] : 0);
