How does os.totalmem work?

os.totalmem is a function in Node.js that retrieves the total amount of system memory in bytes.

When os.totalmem is called, it returns the total amount of physical memory installed on the system, in bytes. This includes both RAM and other types of physical memory, such as swap space.

By using os.totalmem, developers can obtain information about the system's available memory resources, which can be useful for determining whether an application has enough memory to perform a certain task or for optimizing memory usage in general. Note that the value returned by os.totalmem may change over time as memory usage on the system increases or decreases.

const os = require("os");

// Retrieving the total amount of system memory in bytes
const totalMemory = os.totalmem();

console.log(totalMemory); // Outputs: total amount of system memory in bytes

In this example, we're using os.totalmem to retrieve the total amount of system memory in bytes. The totalMemory variable contains the value returned by os.totalmem. Note that the value returned by os.totalmem may be a large number, as it represents the total amount of physical memory installed on the system. If you need to display this value to users or otherwise format it for readability, you may want to convert it to a more human-readable format using appropriate units (such as megabytes or gigabytes) and rounding as needed.
