Passo 96

Instruções

Finalmente, use interpolação de strings para definir o texto do elemento parágrafo como decimalToBinary(${currVal}), onde currVal é a propriedade inputVal do objeto atual. Depois disso, teste seu código inserindo o número 5 no campo de entrada numérica e clicando no botão Convert.

O que fazer:

Testes:

Você deve usar interpolação de string para definir o texto do elemento parágrafo como `decimalToBinary(${obj.inputVal})`.
