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:
var numbers = [10, 50, 8, 220, 110, 11];
numbers.some(function(currentValue) {
return currentValue < 10;
});
// Returns true
some
method inside the checkPositive
function to check if any element in arr
is positive. The function should return a Boolean value.

method.
testString: 'assert(code.match(/\.some/g), "Your code should use the some
method.");'
- text: 'checkPositive([1, 2, 3, -4, 5])

testString: 'assert(checkPositive([1, 2, 3, -4, 5]), "checkPositive([1, 2, 3, -4, 5])
should return true

testString: 'assert(checkPositive([1, 2, 3, 4, 5]), "checkPositive([1, 2, 3, 4, 5])

- text: 'checkPositive([-1, -2, -3, -4, -5])
should return false

testString: 'assert(!checkPositive([-1, -2, -3, -4, -5]), "checkPositive([-1, -2, -3, -4, -5])
