What I learned

This project give me the opportunity to keep learning about Sass. This technology let you nest and write responsive css in a really practical way.

.tip_section {
  display: flex;
  flex-direction: column;
  justify-content: space-between;
  align-items: baseline;
  min-width: 100%;

  &_options {
    display: flex;
    justify-content: space-between;
    width: 100%;

    &_label {
      width: 30%;
      padding: 4px 0px;
      color: $white;
      background-color: $veryDarkCyan;
      border-radius: 5px;
      margin: 5px 0px;
      font-size: 18.5px;
      letter-spacing: 1.5px;
      cursor: pointer;

      @include breakpoints(sm) {
        font-size: 24px;
      }
    }
  }
}

Handling forms has become easier thanks to ES6 syntax.

const handleBlur = (event) => {
  event.target.value === null ||
  event.target.value === "" ||
  event.target.value < 1
    ? setErrors({
        ...errors,
        [event.target.name]: "Can't be zero",
      })
    : setErrors({
        ...errors,
        [event.target.name]: null,
      });
};

const handleChange = (event) => {
  setData({
    ...data,
    [event.target.name]: event.target.value,
  });
};

Continued development

For my next project I would like to divide the logic in differents files and use Typescript.

Useful resources

• Function onChange and onBlur - This is an amazing article which let me reduce code. This funcion helped me listening to changes in all inputs instead of making a function for every one of them.
