How to use If statement within for loops

I am trying to solve the following problem: If there are countries containing 'land', print it as array. If there is no country containing the word 'land', print 'All these are countries without land'. The problem is that when I put if-else statements within the loop it prints all steps in iteration which I do not need. However, outside the loop, I can print only one statement. So where I should put the message when the condition fails? Please help, it seems simple but I couldn't solve it. 

for(let i = 0; i < countries.length; i++){
    if(countries[i].includes('land'))
    arr.push(countries[i])
}
console.log(arr)

you know that if there was atleast one country containing word land then arr will not have length of zero

you can use this length to verify if there was no country found

for(let i = 0; i < countries.length; i++){
    if(countries[i].includes('land'))
    arr.push(countries[i])
}
if(arr.length > 0 )
  console.log(arr);
else
  console.log('All these are countries without land')
