Bubble Sort and Insertion Sort are 2 basic sorting algorithms are there. I implemented these algorithms using JavaScript.

Bubble Sort

const arr = [5,4,3,2,1];

for (let i = 0; i  arr[j 1]) {
            let temp = arr[j];
            arr[j] = arr[j 1];
            arr[j 1] = temp;
        }
    }
}

console.log(arr); // [1,2,3,4,5]

Insertion Sort

it is better than bubble sort if you know the array is almost sorted it is best algorithm

const arr = [5,4,3,2,1];
for (let i = 0; i  arr[j]) {
            const temp = arr[j];
            arr[j] = arr[i];
            arr[i] = temp;
        }
    } 
}


console.log(arr); // [1,2,3,4,5]

Selection Sort

const arr = [5,4,3,2,1];
for (let i = 0; i arr[j]) {
            min = arr[j];
            pos = j;
        }
    }

    const temp = arr[i];
    arr[i] = arr[pos];
    arr[pos] = temp;
}


console.log(arr); // [1,2,3,4,5]
