What would I do if I want to search an array for certain variables + display those

Hi all, what would be the code for the following example:

Display all students who took the HTML course. OR: Display all students who took the HTML course AND have results >80%.

Any ideas? Cheers, Nicole

The button above links to the video on creating a question/answer quiz program. But assuming that you're talking about an array of objects representing students with various properties, here would be some generic approaches to your objectives:

// Display all students who took the HTML course
for (let i=0; i < students.length; i++) {
  if (students[i].courses.includes('HTML')) displayStudent(students[i]);
}

// Display all students who took the HTML course AND have results >80%
for (let i=0; i < students.length; i++) {
  if (students[i].courses.includes('HTML') && students[i].results > 80)
    displayStudent(students[i]);
}
