Creating Dynamic Variable in JavaScript

In JavaScript, the dynamic variable is nothing but names that do not have a specific name hard-coded in our script, and they are named dynamically with string values from other sources. It is rarely used in JavaScript, but in some cases, they are very useful. 

We have the simplest JavaScript method to create the dynamic variables to create an array. We can define the dynamic array without defining its length and use it as Map in implementation. The key uses an array by mapping the values and also accessing the value using a key. Dynamic variables execute statements and logical expressions by computing their own values. A dynamic variable assigns itself the result of a calculation or operation, and its dynamic variable types are dynamic string, dynamic number, and dynamic True/False (Boolean). A dynamic variable is that its value can change while the application runs by distinguishing characteristics. For example, our application might maintain a threshold value compared to a field value in each tuple processed. 

Types of variables in JavaScript: 

1. Local Variable. 
2. Global Variable. 

Here is an example of how to create a dynamic variable in JavaScript:

Instructions

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 hope you found this useful.

I found this code snippet by searching for 'how to create dynamic variable 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 dynamic variables 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 dynamic variables in javascript.
