Asking for advice on the compatibility of WeChat applet:

I write a WeChat applet here, and then it uses wx.canIuse to detect whether some APIs can be used. So I put the basic library of the mini program

The version is set to 1.1.1

I would like to ask, if a lower version of WeChat client (not compatible with 1.1.1) opens my small program, will it cause an error?

In order to prevent such a problem from happening, I decided to check the WeChat version first, and then give a prompt as long as the version is lower than what it is. But I don’t know at all

How to obtain the relationship between the WeChat version and the WeChat applet basic library. .
