The following code function steamrollArray(arr) { // I'm a steamroller, baby return arr.flat(); } steamrollArray([1, [2], [3, [[4]]]]); returns arr.flat is not a function I tried it in Firefox and Chrome v67 and the same result has happened. What's wrong? The flat method is not yet implemented in common browsers (only Chrome v69, Firefox Nightly and Opera 56). It’s an experimental feature. Therefore you cannot use it yet . You may want to have your own flat function instead: Object.defineProperty(Array.prototype, 'flat', { value: function(depth = 1) { return this.reduce(function (flat,

I created QPushButton in Qt Designer with this stylesheet: QPushButton#pushButton { background-color: #ffffff; } QPushButton#pushButton:disabled { background-color: yellow; } QPushButton#pushButton:pressed { background-color: orange; } QPushButton#pushButton:focus:pressed { background-color: black; } QPushButton#pushButton:focus { background-color: green; } QPushButton#pushButton:hover { background-color: red; } QPushButton#pushButton:checked { background-color: pink; } It Works, but when i check "flat" in the properties, then it doesn't work anymore, I would like to ask you why? And how can i

SSIS does 2 things in relation to handling flat files which are particularly frustrating, and it seems there should be a way around them, but I can't figure it out. If you define a flat file with 10 columns, tab delimited with CRLF as the end of row marker this will work perfectly for files where there are exactly 10 columns in every row. The 2 painful scenarios are these: If someone supplies a file with an 11th column anywhere, it would be nice if SSIS simply ignored it, since you haven't defined it. It should just read the 10 columns you have defined then skip to the end of row marker, but

I've looked around the internet and haven't quite found what I'm looking for. I have a flat array with each element containing an 'id' and a 'parent_id'. Each element will only have ONE parent, but may have multiple children. If the parent_id = 0, it is considered a root level item. I'm trying to get my flat array into a tree. The other samples I have found only only copy the element to the parent, but the original still exists. EDIT Each element of the starting array is read from a separate XML file. The file itself will have '0' as the value for parent_id if it doesn't have a parent. The
