This solution runs a while loop that pushes each element into a new array. When the next element of an array is a nested array, the function recursively calls itself and does the same for its

May 9, 2015 I found myself wanting to flatten an array of arrays while writing some Python code earlier this afternoon and being lazy my first attempt involved

Below are the Parameters of JavaScript Flatten Array: [depth]: depth specifies how deep the nested array structure is and which should be flattened. By default, depth will be 1. Returns new array according to depth specified with sub-array elements concatenated. function flatten (ary) { return ary.reduce (function (a, b) { if (Array.isArray (b)) { return a.concat (flatten (b)) } return a.concat (b) }, []) } Let's adopt some ES6 syntax which makes it even shorter, in one line. const flatten = (ary) => ary.reduce ((a, b) => a.concat (Array.isArray (b) ? flatten (b) : b), []) This solution runs a while loop that pushes each element into a new array. When the next element of an array is a nested array, the function recursively calls itself and does the same for its function flatten (arr) { return [].concat (arr) } Is simply expands arr and passes it as arguments to concat (), which merges all the arrays into one.

Nodejs flatten array of arrays

A trick when you want to flatten a matrix X of shape (a,b,c,d) to a matrix X_flatten of shape (b ∗∗ c ∗∗ d, a) is to use: X_flatten = X.reshape(X.shape[0], -1). Använd np.ravel (för en 1D-vy) eller np.ndarray.flatten (för en 1D-kopia) eller np.ndarray.flat (för en 1D-iterator): In [12]: a = np.array([[1,2,3], [4,5,6]]) In [13]: b a = np.arange(9)+1 b = np.array([a*10**-1, a*10**0, a*10**1, a*10**2, a*10**3]).flatten() b = np.append(b, 10000) In [84]: b Out[84]: array([ 1.00000000e-01, Flat light conditions.

Om jag till exempel har en matris, [1, 3, 2, 4, 5] , function(array, n=3) skulle returnera indexen [4, flat = ary.flatten() indices = np.argpartition(flat, -n)[-n:] indices

Flatten array with objects into 1 object, Use Object.assign : let merged = Object.assign(arr); // ES6 (2015) syntax Apr 15, 2019 flat() method to us. Its rules are simple - it simply flattens your nested array by specified depth (defaults to 1), effectively leaving you with an array arr.flat([depth]);. The method takes a parameter as depth.

There is also the Array.prototype.flat() method (introduced in ES2019) which you could use to flatten the arrays, although it is only available in Node.js starting with version 11, and not at all in Internet Explorer.
