- [Instructor] Starting with Chrome,…we also have available an API…to check device's memory.…That is the available memory,…the RAM memory available…in the current user's device.…Compatibility might change with the future…but today it's only on Chromium-based browsers…and it will give you a number expressing gibibytes.…So remember gibibytes is basically 1024 mebibytes.…So it's basically roughly what we know of gigabytes…but it's a binary version of that.…
To use the API it's just getting navigator…the deviceMemory that's all.…And we're going to get the amount of gigabytes…out of float number.…It can be left on one for example at 0.5.…And typically the minimum value…that we will get it's 0.25 gibibytes.…Then if we have one or less than one…it means it's a low-end device…like a very cheap or old android.…From one to two gibibytes it's a mid-end device.…
Two to four a high-end device.…It can also be a tablet.…And from four to eight it's probably a desktop.…This is important because…even if you're desktop computer…or your laptop has 32 gigabytes of RAM…
