Question

JavaScript    Open      yourmain.jsfile.  Create      an array of 5 arrays.  Each      inner array should contain a name and a numerical grade between 1 and 100.  Create      a function called getGrade with a parameter of grade.     Inside       the above function, create an if/else statement that accounts for grades       and their respective values from F to A.    Create      a for loop that iterates through the length of the students' array and      increments by 1 with each loop.     Inside       that for loop, use document.write(//your statement); to output a string       of text that reads like the following example:   David's       number grade is 80 and letter grade is a B.

let grades = [['David', 80], ['Victor', 77], ['Tracey', 55],
              ['Jason', 95], ['Raymond', 69]];
              
function getGrade(numericalGrade)
{
  if(numericalGrade >= 90)
    return 'A';
  else if(numericalGrade >= 80)
    return 'B';
