Soluation:

In Javascript:

var average = function(salary) {

    let maxSalary= salary[0], minSalary= salary[0], sum=0, count = 0;

    for(let i=0; i<salary.length; i++){

      if(maxSalary<salary[i])

        maxSalary = salary[i];

      if(minSalary>salary[i]){

        minSalary = salary[i];

      }

    }

    for(let i=0; i<salary.length; i++){

      if(maxSalary != salary[i] && minSalary != salary[i]){

        sum += salary[i];

        count++;

      }

    }

    let result = sum/count;

    return result;

    

};
