Write a function that accepts an array of test scores as an argument then the function should return a number of scores that 80 or higher? [duplicate]

This question already has an answer here:

I'm still pretty new into JS but I'm having a hard time with this problem. I'm sure the answer is somewhat simple but i can't figure out what to put into the function expression after i've made my array of scores? Do i need to do a for loop?
Thanks

let array = [20,30,40,50,60,70,80,92,93,95,98,100]

function testScores(array){

}

you can use array's filter method. please follow below definition.

function testScores(array){
return array.filter(ele=>ele>=80)
}


testScores

function testScores(array){
return array.filter(number => number >= 80);
}


This will return an array of scores more 80 and above.
e.g

let scores = [20,30,40,50,60,70,80,92,93,95,98,100];
testScores(scores)


If you just want the count of scores more than 80 you can do

testScores(scores).length


testScores
