Day 5 Level 1 Q14

[Harufuu]

let itCompanies = [
    "Facebook",
    "Google",
    "Microsoft",
    "Apple",
    "IBM",
    "Oracle",
    "Amazon"
  ]
// Filter out companies which have more than one 'o' without the filter method

I solve it with the For loop, something like this

let filtered_array = [];
for(i = 0; i < itCompanies.length; i++) {
  let thing = itCompanies[i];
  if(thing.indexOf("o") !== thing.lastIndexOf("o")){
    filtered_array.push(thing);
  }
}

console.log(filtered_array) // [ 'Facebook', 'Google', 'Microsoft' ] 

The problem is that the loop stuff would first appear in the course on Day 6, while this is a question in the Day 5 exercise. So, I wonder if there is a solution that does not involve either the filter method or the loop.

So all we just have to do is when you a question and it so confusing just leave it blank and move on with the next one then come back to that question again when you have more confidence.

@Harufuu Here, it may help you.

let itCompanies = ['facebook', 'google', 'microsoft',  .....]
var newArray = []
itCompanies.map((v,i)=>{
if(v.includes('o')){
newArray.push(v);
}
})
console.log(newArray); // [items with o will be added here.]
