Adicionar itens usando splice ()

  • Usando a função splice (), você deve remover os 2 primeiros elementos de matriz arr e substituí-los com DarkSalmon e BlanchedAlmond .
  • Lembre-se de que a função de emenda pode levar até três parâmetros.

Exemplo:

arr.splice(0, 1, "Two"); 
 /*  The first two paramemters are the same as they were in the previous challenge. 
    `0` will start the `splice()` function off at index 0. 
    The second parameter `1` will remove only 1 variable from the array. 
    The final variable "Two" will replace the variable in arr[0]. 
    Note: The final parameter can take more than 1 arguement. 
 */ 

Solução:

function htmlColorNames(arr) { 
  // change code below this line 
  arr.splice(0, 2, "DarkSalmon", "BlanchedAlmond"); 
  // change code above this line 
  return arr; 
 } 
 
 // do not change code below this line 
 console.log(htmlColorNames(['DarkGoldenRod', 'WhiteSmoke', 'LavenderBlush', 'PaleTurqoise', 'FireBrick']));
