--description--
The every
method works with arrays to check if every element passes a particular test. It returns a Boolean value - true
if all values meet the criteria, false
if not.
For example, the following code would check if every element in the numbers
array is less than 10:
const numbers = [1, 5, 8, 0, 10, 11];
numbers.every(function(currentValue) {
return currentValue < 10;
});
The every
method would return false
here.
--instructions--
Use the every
method inside the checkPositive
function to check if every element in arr
is positive. The function should return a Boolean value.
--hints--
Your code should use the every
method.
assert(__helpers.removeJSComments(code).match(/\.every/g));
checkPositive([1, 2, 3, -4, 5])
should return false
.
assert.isFalse(checkPositive([1, 2, 3, -4, 5]));
checkPositive([1, 2, 3, 4, 5])
should return true
.
assert.isTrue(checkPositive([1, 2, 3, 4, 5]));
checkPositive([1, -2, 3, -4, 5])
should return false
.
assert.isFalse(checkPositive([1, -2, 3, -4, 5]));
