The name, comes from the words "Code" and "Competition".

Codecom is being developed using the Performance API to measure the execution time of JavaScript code and to display the results both within the terminal and in an HTML file, allowing them to be viewed in the browser as well.

When developing a software, usually, attention is not paid to the milisecond-level execution time of the code. However, in some cases;

• When the application will run on a device with limited resources.
• When evaluating and improving the performance of the code.
• When processing big data, deciding on the optimal solution method.
• When comparing the performance of different codes.
• When seeking to enhance the user experience by reducing the waiting time of the user.

In such cases, it is necessary to measure the execution time of the code and to compare the results.

Codecom, is being developed to make this process easier and more enjoyable.

• No dependencies
• Easy to use
• No magic
• Just simple use and effective

npm install codecom

Create a new file named codecom.mjs in the root directory of your project and add the following code into it.

import codecom from 'codecom'

To test code,

• Add the // _start() code to the beginning of where your code's scope start.
• Add the // _end() code to the end of where your code's scope end.

// _start()
for (let i = 0; i < 100000; i++) {
  console.log(i)
}
// _end()

Add the following code to the script object in the package.json file.

"codecom": "node --watch codecom.mjs"

Run the following command in the terminal.

npm run codecom

Note

• Automatically the codecom.html file will be created in the root directory of your project.

Tip

• If you want to open automatically the codecom.html file in the browser, you can add the following code to the script object in the package.json file.

"codecom:open": "node --watch codecom.mjs"

and run following command.

npm run codecom:open

Results will be displayed in the terminal and in the codecom.html file.

Terminal result

Browser result
