get system cpu frequency in javascript

To get the system CPU frequency in JavaScript using Node.js, you can use the built-in os module.

Here's some example code that retrieves the CPU frequency:

index.tsx
const os = require('os');

const cpuFrequency = os.cpus()[0].speed;
console.log(`CPU Frequency: ${cpuFrequency} MHz`);
119 chars
5 lines

The os.cpus() function returns an array of CPU information with each element representing a logical CPU core. The speed property of the object at index 0 represents the CPU frequency of the first CPU core.

Note that the CPU frequency is not a constant value and can fluctuate depending on a number of factors such as CPU load and power management settings.
