This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The deviceMemory read-only property of the navigator interface returns the approximate amount of device memory in gigabytes. This value is an approximation given by rounding down to the nearest power of 2 and dividing that number by 1024. Also, the lower and upper bounds are used to protect privacy of owners of very low- or high-end devices.
Syntax
const memory = navigator.deviceMemory
console.log ("This device has at least " + memory + "GiB of RAM.")
Value
A floating point number.
