ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac...

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn...

i not sure when use pool of workers vs multiple processes. processes = [] m in range(1,5): p = process(target=some_function) p.start() processes.append(p) p in processes: p.join() vs if __name__ == '__main__': # start 4 worker processes pool(processes=4) pool: pool_outputs = pool.map(another_function, inputs) as says on pymotw : the pool class can used manage fixed number of workers simple cases work done can broken , distributed between workers independently. the return values jobs collected , returned list. the pool arguments include number of processes , function run when starting task process (invoked once per child). please have @ examples given there better understand application, functionalities , parameters. basically pool helper, easing management of processes (workers) in cases need consume common input data, process in parallel , produce joint output. the pool quite few thi...
