lodash exclude property from object
The iteratee is bound to thisArg and invoked with three arguments:(value, index|key, collection).If a property name is provided for iteratee the created _.property style callback returns the property value of the given element.If a value is also provided for thisArg the created _.matchesProperty style callback returns true for elements that have a matching property value, else false.If an object is provided for iteratee the created _.matches style callback returns true for elements that have the properties of the given object, else false. The key feature is the old void(0) which resolve to undefined. Lodash has a `filter()` function that lets you filter an array using a custom function. What is the most elegant way to remove an array of properties from an object immutably in JavaScript? The corresponding value of each key is the number of times the key was returned by iteratee. Iterates over elements of collection invoking iteratee for each element. This method performs a stable sort, that is, it preserves the original sort order of equal elements. My issue with the accepted answer, from an ESLint rule standard, if you try to destructure: the 2 new variables, notNeeded and alsoNotNeeded may throw a warning or error depending on your setup since they are now unused.
