JS: Filter array only for non-empty and type of string values

Question

I am trying to filter an array like this:

array.filter(e => { return e })

With this I want to filter all empty strings including undef

Answer 1

When returning a method that consists of one line as a callback in es6 there is no need for return as this happens implicitly.

Hope this helps :-)

let arr = ["", "", "fdsff", [], null, {}, undefined];

let filteredArr = arr.filter(item => (typeof item === "string" && !item) || !item)
                  
console.log(filteredArr)
