Multi outputs support

[ghost]

Hello there! The project is really cool~

I want to make an issue

When multiple returns are written in the code, you need to determine if the code can be executed.

like this:

 /**
 * Binary search
 * @param {Array} list
 * @param {Number} element
 * @returns {number}
 */
function indexSearch(list, element) {
    let currentIndex,
        currentElement,
        minIndex = 0,
        maxIndex = list.length - 1;

    while (minIndex <= maxIndex) {
        currentIndex = Math.floor((maxIndex + maxIndex) / 2);
        currentElement = list[currentIndex];

        if (currentElement === element) {
            return currentIndex;
        }

        if (currentElement < element) {
            minIndex = currentIndex + 1;
        }

        if (currentElement > element) {
            maxIndex = currentIndex - 1;
        }
    }
 

  // Please pay attention to these two sentences
  return -1;
  return 0;
}

There are two returns at the end of the code block. According to the actual situation, the last return will never be executed.

But in the flow chart, the effect is that the second one can still be executed.

Expectations: Ability to present special styles for code that can never be executed.

thanks!

Hi @IceyTea, thanks for the reporting; you can use "custom modifiers" (see Readme, https://github.com/Bogdan-Lyashenko/js-code-to-svg-flowchart#flow-tree-modifier, https://github.com/Bogdan-Lyashenko/js-code-to-svg-flowchart#shapes-tree-editor) to do so (i.e. you need to define that rule when you use 'js-code-to-svg-flowchart') there is no native support right now. It's definitely doable, but unfortunately I don't have time now for adding more features to this project; if you are interested in contributing - I definitely will help&guide you so you can implement this feature. Thanks.
