Distinct Array JS Fundamentals

function distinctArray(arr) {
    let uniqueElements = [];

    for (let i = 0; i < arr.length; i++) {
      if (uniqueElements.indexOf(arr[i]) === -1) {
        uniqueElements.push(arr[i]);
      }
    }

    console.log(uniqueElements.join(' '));
}

OR

function distinctArray(arr) {
    let uniqueElements = arr.filter((element, index) => arr.indexOf(element) === index);

console.log(uniqueElements.join(' '));
}

OR

function distinctArray(arr) {
    let newArr = [];
    for (let i = 0; i < arr.length; i++) {
        let element = arr[i];
        let index = arr.indexOf(element);
        if(newArr.indexOf(element) !== index) {
            newArr.push(element);
        }
    }
    console.log(newArr.join(' '));
