I want to input an array of arrays, but then pick them apart. so for example I have an array of locations so like multiple coordinates of latitude and longitude. but I want to write a loop that will then take that array of arrays and make and array for all of the latitude coordinates and all of the longitude coordinates.

so for example if I had

input = [[45,45],[35,75][85,90]] it would make 2 arrays as my output [45,35,85] and [45,75,90]

You could transpose the array and take lat and long as single arrays.

var input = [[45, 45], [35, 75], [85, 90]],
[lat, long] = input.reduce((r, a) => a.map((v, i) => (r[i] || []).concat(v)), []);

console.log(lat);
console.log(long);
.as-console-wrapper { max-height: 100% !important; top: 0; }

Learn JavaScript Multidimensional Array By Examples, This tutorial shows you how to create a JavaScript multidimensional array by using an array of To show the activities array in the console, you use the console.table() method as follows: console.tables(activities);. The following illustrates the output: In this tutorial, you have learned how to use an array of arrays to create a  I am trying to write a function in Julia that takes in a multi-dimensional array (a data cube) and rescales every entry from 0 to 1. However, whenever I run the code in atom, I get the error

Try this, loops over every coordinate and puts the first value from each coordinate into the array called first and the second value from each coordinate into an array called second ..

var input = [[45,45],[35,75],[85,90]];

function splitValues(coordinates) {
var first = [];
var second = [];
for (var i = 0; i < coordinates.length; i++) {
first.push(coordinates[i][0]);
second.push(coordinates[i][1]);
}
}

splitValues(input);

Multidimensional array in JavaScript, So multidimensional arrays in JavaScript is known as arrays inside another array. 1D array contains some digits. Multidimensional-Dimensional array: Method 1: If we print the entire 4th sub-array, document.write(salary[3]); // the output will  For this reason, we can say that a JavaScript multidimensional array is an array of arrays. The easiest way to define a multidimensional array is to use the array literal notation. To declare an empty multidimensional array, you use the same syntax as declaring one-dimensional array: let activities = [];

This will help assuming you will always have a 2 values array in input and you want only 2 results

const array = [[45,45],[35,75],[85,90]]
let first = []
let second = []
array.forEach((item)=>{
first.push(item[0])
second.push(item[1])
})
console.log(first)
console.log(second)

How to create two dimensional array in JavaScript?, It contains well written, well thought and well explained computer science and The two-dimensional array is a collection of items which share a common from an array in JavaScript · How to take user input for two dimensional (2D) array in PHP ? Create a Reflex Game using JavaScript · How to create a function from a  Can anyone give me a sample/example of JavaScript with a multidimensional array of inputs? Hope you could help because I'm still new to the JavaScript. Like when you input 2 rows and 2 columns the output of it will be 2 rows of input and 2 columns of input. Like this: [input][input] [input][input]

Arrays, There are two syntaxes for creating an empty array: We can use it for multidimensional arrays, for example to store matrices: toString. Arrays have their own implementation of toString method that returns a comma-separated list of elements. The input is an array of numbers, e.g. arr = [1, -2, 3, 4, -9, 6] . Since we don't know what you have done so far, this is an approach using the native Array.prototype.map method which is very useful to understand. It allows you to iterate over an array and return a new array that has the same number of elements that have possibly been transformed by the supplied function.

5. Working with Arrays and Loops, You can also create, and use, a literal array in a function or method call: var arrObject = new Array(); arrObject[0] = "cat"; // array now has one element Multidimensional arrays in JavaScript are managed by creating a new array as an element 1:</label> <input type="text" id="first" /><br /> <label>Value 2:</​label> <input  Write the function sumInput() that: Asks the user for values using prompt and stores the values in the array. Finishes asking when the user enters a non-numeric value, an empty string, or presses “Cancel”. Calculates and returns the sum of array items. P.S. A zero 0 is a valid number, please don’t stop the input on zero. Run the demo. solution
