To create a variable from an array value, use the extract() function. It converts array keys into variable names and array values into variable values. The extract() function also imports variables from an array to the symbol table in JavaScript.


Methods to create a variable from an array in JavaScript: 

  1. The creation of a variable does in the first line called result, and it assigns an empty array to it. 
  2. The number of observations in the data set is denoted as N, a reserved variable. 
  3. To iterate through all the N values, a loop is used. 
  4. The array from the JavaScript variable is returned in the final line. 

To get a value from an array, the array.value() function is used, and it is a built-in function in JavaScript that is used to return a new array iterator object that contains the values for each index in the array. It prints all the elements of the array and returns values of a new array iterator object, that is, elements of the given array. 

Here is an example of how to create a variable from an array of values in JavaScript: 

Fig : Preview of the output that you will get on running this code from your IDE.



Follow the steps carefully to get the output easily.

  1. Install JavaScript ES6 code snippet and Code Runner from Extension on your IDE(We use Visual Studio Code).
  2. Copy the snippet using the 'copy' and create one new file filename.js(eg.test.js) then paste the code in that JavaScript file.
  3. Save the file and run the file using run button to generate the output.

I found this code snippet by searching for 'how to create variable from array values in js' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created and tested in Visual Studio Code 1.74.1.
  2. JavaScript ES6 Code Snippet version v1.8.0.
  3. Code Runner version v0.11.8.

Using this solution, we are able to create variable from array values in javascript with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to create variable from array values in javascript.
