VisualizaçõesJavascript filter function is returning the removed element and not the new array
I am simply trying to remove an element from an array in javascript using the filter function. However, after running this function, newArray is an array with only 1 element - the one I removed.
I wanted an array with the original elements but minus the one I want to remove. How do I get that?
var newArray = comments.filter((comment) => comment.idComment == action.idSectionComments);

You are not removing the element, you are picking it. The filter function return all elements in array that satisfy the condition, so you have to reverse the condition to filter all elements that doesn't match the id
var newArray = comments.filter((comment) => comment.idComment !== action.idSectionComments);

Maybe reverse:
var newArray = comments.filter((comment) => comment.idComment !== action.idSectionComments);
