I am working on a javascript mini-project where users have to enter a number.
That number is an endpoint of coordinates. Last coordinate I will store in my array will be in format of [number, number]
For example, that number is 3.
I have to store this in an array.
[1,1], [1,2], [1,3], [2,1], [2,2], [2,3], [3,1], [3,2], [3,3]
For example, if number is 4, array need to looks like this: [1,1], [1,2], [1,3], [1,4], [2,1], [2,2], [2,3], [2,4] [3,1], [3,2], [3,3], [3,4], [4,1], [4,2], [4,3], [4,4]
I hope you understand what I need. Any help?
You just need two nested loops for this to work. In the code below, i variable represents the first number in the miniarray element, while j represents the second one. For each value of i, j will run n times and result in the array you want as follows:
let n = 3;
let arr = [];
for(let i=1; i<=n; i++){
for(let j=1; j<=n; j++){
arr.push([i, j]);
}
}
console.log(arr);Using nested loops ... Try this one
function generateArray(int) {
let array = [];
let initial = 1;
let numbers = [];
while (initial <= int) {
numbers.push(initial);
initial++;
}
let finalArr = [];
numbers.forEach(number => {
let i = 1;
while (i <= numbers.length) {
array.push([number, i]);
i++;
}
});
return array;
}
console.log(generateArray(4))
Please use the following javascript code snippet.
num = 5
arr=[]
for(i=1;i<=num;i++){
for(j=1;j<=num;j++){
temparr=[i,j]
arr.push(temparr)
}
}
console.log(arr)
