问题 So far I tried this but it returns unfiltered array: function filterRangeInPlace(array, min, max) { array = array.filter(item => (item >= min && item <= max)); console.log(array); } let arr = [5, 3, 8, 1]; filterRangeInPlace(arr, 1, 4); console.log(arr); 回答1: If it's actually important to do the filtering in-place without creating another array, you have to go sort-of old school and iterate through the array with two indexes, copying values along the way.

问题 I'm having an argument with a co-worker about done() in Jest tests. He's orders of magnitude more experienced with JavaScript than I am, and I came in after async / await was generally accepted, plus came from a .NET environment, so I was used to it. I write my tests like this: it("should return 200 OK for POST method", async () => { await request(app).post("SOMEENDPOINT") .attach("file", "file") .expect(200); }); He's more used to promises so will write his tests like this: it("should return

问题 I am using Python 2.7.3. Can anybody explain the difference between the literals: '\u0391' and: u'\u0391' and the different way they are echoed in the REPL below (especially the extra slash added to a1): >>> a1='\u0391' >>> a1 '\\u0391' >>> type(a1) <type 'str'> >>> >>> a2=u'\u0391' >>> a2 u'\u0391' >>> type(a2) <type 'unicode'> >>> 回答1: You can only use unicode escapes ( \uabcd ) in a unicode string literal.

问题 This question already has answers here : Why does Date.parse give incorrect results? (11 answers) Closed 4 years ago . I feel like I am missing something here.
