 //for getting AVG of an array
let avg = aggregateFunctions.avg(array);

 //for getting MAX of an array
let max = aggregateFunctions.max(array);

 //for getting MIN of an array
let min = aggregateFunctions.min(array);

 ### SOME EXAMPLES
  
```javascript
    let exapmpleArray = [7, 20, 24, 14, 2, 19, 12]

    //for getting SUM of an array
    let sum = aggregateFunctions.sum(exapmpleArray);
    console.log(sum);//98

    //for getting AVG of an array
    let avg = aggregateFunctions.avg(exapmpleArray);
    console.log(avg);//14

    //for getting MAX of an array
    let max = aggregateFunctions.max(exapmpleArray);
    console.log(max);//24

    //for getting MIN of an array
    let min = aggregateFunctions.min(exapmpleArray);
    console.log(min);//2

    //for getting COUNT/LENGTH of an array
    let count = aggregateFunctions.count(exapmpleArray);
    console.log(count);//7
