Challenge: Select Specific Data Using filter()
Task
Given an array of student objects, use the filter()
method to create a new array called highScorers
that includes only the students with exam scores greater than or equal to 90.
- The original array is given as
students
, containing objects representing students with propertiesname
andscore
. - Check if the student's score is greater or equal to 90.
- Use the
filter()
method on thestudents
array to create a new array,highScorers
, that includes only the students with high scores.
123456789101112131415const students = [ { name: "Alice", score: 92 }, { name: "Bob", score: 87 }, { name: "Charlie", score: 95 }, { name: "David", score: 78 }, { name: "Emma", score: 90 }, ]; const highScorers = students.___((___) => { return ___; }); for (let i = 0; i < highScorers.length; i += 1) { console.log(highScorers[i].name); }
Expected output:
Alice
Charlie
Emma
The filter()
method will create a new array by including only the elements that satisfy the condition specified in the callback function.
