How to filter arrays with a for loop without the filter function?

December 19, 2021

Our task is to write a function which filters a list of human names. The result should be only names without a hyphen ("-").

The only ideas I have till now:

let names = ['Marc', 'Stephen-Peter', 'Lisa', 'Marie-Tina', 'Philip']; 


function filter (arr) {
    for (let i = 0; i < arr.length; i++) {
        ??????;
    }
    return ???;
}

console.log(???); 

//The result should be only Marc, Lisa, Philip

My ideas were to use charAt and check every word for a "-" but then I don’t know how to prevent that the whole name with the hyphen is not inside the new filtered array. I thought about two for loops I don’t know how to do that.

>Solution :

first the array items need to be inside single or double quotes
let names = [‘Marc’, ‘Stephen-Peter’, ‘Lisa’, ‘Marie-Tina’, ‘Philip’];

 function filter (arr) {
        let result = []
        for (let i = 0; i < arr.length; i++) {
           if(!arr[i].includes('-')) {              
               result.push(arr[i])
           }
        }
        return result
    }
    
    console.log(filter(names))
