I am trying to generate two random values and store them in an array however I would like them to be different values each time a random number between 0-3 is generated.
function new_Randomvalues(n) {
var array1 = [];
for (var i = 0; i < n; i++) {
var row = Math.round(3*Math.random());
var col = Math.round(3*Math.random());
array1.push([row,col]);
}
return array1;
}
console.log(new_Randomvalues(10));
How do I edit this function where if an array of same numbers are pushed into array1 then remove those and generate 10 unique coordinates. Help would be appreciated thanks
Per sam's question in the comments, here's the code:
function shuffle(array) {
for (var i = array.length - 1; i > 0; i--) {
var j = Math.floor(Math.random() * (i + 1));
var temp = array[i];
array[i] = array[j];
array[j] = temp;
}
}
pairs = [];
for (let i = 0; i <= 3; i++) {
for (let j = 0; j <= 3; j++) {
pairs.push([i, j]);
}
}
shuffle(pairs);
pairs = pairs.slice(0, 10);
console.log(pairs);
