Remove Duplicates

Given an array find and remove Duplicates

Example
let arr1 = [1, 1, 2, 3, 3, 100, 3, 7, -4]; => [ 1, 2, 3, 100, 7, -4 ] let arr2 = [‘Hi’, ‘Hello’, ‘Hi’, ‘Hey’,’Hi’]; => [ ‘Hi’, ‘Hello’, ‘Hey’ ]

function removeDuplicates(arr) {
  let result = [];

  for (let x of arr) {
    if (!result.includes(x)) {
      result.push(x)
    }
  }
  return result;
}

console.log(removeDuplicates(arr1))
console.log(removeDuplicates(arr2))

We create function called removeDuplicates with parameter arr and local variable result = []

We loop the array given into the parameter arr with while loop with for of loop for(let x of arr)

Inside the for loop we check if(!result.includes(x)) and if true result.push(x)

In the end we return result
