JavaScript has a lot of Array iteration patterns that help developers write clean and read code. In Javascript, we have many methods for an array that iterates for each element in an array and can be used according to our purpose of iteration. You can even iterate an array using a simple...
The following code iterates an array (arr), and extracts and prints the index and elements.// creating an array const arr = ["New Delhi", "New York", "California", "London"]; // Iterating an array with index and element for (const [key, value] of arr.entries()) { console.log...
In basicforloops, iterating through each scalar of an array we need to usenforloops which can be difficult to write for arrays with very high dimensionality. Example Iterate through the following 3-D array: importnumpyasnp arr = np.array([[[1,2], [3,4]], [[5,6], [7,8]]]) ...
function getValues(array) local i = 0 return function() i = i + 1; return array[i] end end -- initialize an array with values array = {"a", "b", "c", "d", "e", "f"} -- iterate using custom function for value in getValues(array) do -- print the value print(value) ...
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' ); var cueveryByRight = require( '@stdlib/array-base-cuevery-by-right' ); function isPositive( value ) { return ( value > 0 ); } // Create an array of random values: var x = discreteUniform( 10, -10, 10 )...

To do this, we need to use a nested for loop, in which the variable i represents rows, and j represents the columns. In this case, each myMatrix[i] also represents an array, therefore we also need to iterate each position of myMatrix[i] in the nested for loop. We can output the...

Because it's working on a plain array, $.map() returns a plain array and .get() does not need to be called – in fact, it will throw an error as it's not a native JavaScript method. A word of warning: $.map() switches the order of callback arguments. This was done in order...
Apply a function to elements in two input arrays while iterating from right to left and assign the results to an output array. - GitHub - stdlib-js/utils-map2-right: Apply a function to elements in two input arrays while iterating from right to left and
