--description--
The some
method works with arrays to check if any element passes a particular test. It returns a Boolean value - true
if any of the values meet the criteria, false
if not.
For example, the following code would check if any element in the numbers
array is less than 10:
const numbers = [10, 50, 8, 220, 110, 11];
numbers.some(function(currentValue) {
return currentValue < 10;
});
The some
method would return true
.
--instructions--
Use the some
method inside the checkPositive
function to check if any element in arr
is positive. The function should return a Boolean value.
--hints--
Your code should use the some
method.
assert(__helpers.removeJSComments(code).match(/\.some/g));
checkPositive([1, 2, 3, -4, 5])
should return true
.
assert(checkPositive([1, 2, 3, -4, 5]));
checkPositive([1, 2, 3, 4, 5])
should return true
.
assert(checkPositive([1, 2, 3, 4, 5]));
checkPositive([-1, -2, -3, -4, -5])
should return false
.
assert(!checkPositive([-1, -2, -3, -4, -5]));
