ds-algo-study/DS-n-Algos/ALGO/UNSORTED/Falsy Bouncer.js

Just experimenting with publishing a package

function bouncer(arr) {
    return arr.filter(Boolean);
  }
  console.log(bouncer([8, "Hello", "", false, null, undefined, 9, NaN, "World", 0]));

 //Boolean is a funciton that returns truthy when true and falsy when false.
 //Boolean(7) return true, Boolean("") returns false and so on
 //This get run once per item in the array and filter only keeps the value which is true

 //Solution1:
// function bouncer(arr){
//     let newarray = [];
//     for(let i=0; i<arr.length; i++) { 
//     if(arr[i]){
//         newarray.push(arr[i])
//     }
//     }
//     return newarray
// }
