【Edabit 算法 ★☆☆☆☆☆】 Is the Number Less than or Equal to Zero?

language_fundametals validation conditions

Instructions

Create a function that takes a number as its only argument and returns true if it’s less than or equal to zero, otherwise return false.

Examples

lessThanOrEqualToZero(5) // false
lessThanOrEqualToZero(0) // true
lessThanOrEqualToZero(-2) // true

Notes

• Don’t forget to return the result.

Solutions

function lessThanOrEqualToZero(num) {return num <= 0 ;
}

TestCases

let Test = (function(){return {assertEquals:function(actual,expected){if(actual !== expected){let errorMsg = `actual is ${actual},${expected} is expected`;throw new Error(errorMsg);}}}
})();Test.assertEquals(lessThanOrEqualToZero(5), false)
Test.assertEquals(lessThanOrEqualToZero(0), true)
Test.assertEquals(lessThanOrEqualToZero(-5), true)
