0065【Edabit ★☆☆☆☆☆】【字符串长度的是奇数还是偶数】Is the String Odd or Even?

conditions strings validation

Instructions

Examples

oddOrEven("apples") // true
// The word "apples" has 6 characters.
// 6 is an even number, so the program outputs true.
oddOrEven("pears") // false
// "pears" has 5 letters, and 5 is odd.
// Therefore the program outputs false.
oddOrEven("cherry") // true

Notes

• N/A

Solutions

function oddOrEven(s) {
	return s.length % 2 == 0;
}
