I found that JS, python, VBS, VBA, VB6, many languages are similar to scripts, which do not need to specify the ,type of variables.variant,So VB6's route was correct.
But Microsoft completely abandoned him. VB. Net, mandatory declaration of variable types, very long syntax.
It can be said that it deviates too much from VB6.
Just like when we drive too close, the anti-collision system will automatically turn on.

If you accidentally doze off, he will also remind you. It also has an automatic driving system.

Without specifying the type of the variable, it runs a little slower, but the more powerful the CPU is, the more it makes up for.
In fact, if Microsoft takes a little time. Adding multithreading to VBA or VB6 can take less than a week, or even a day.

As long as he doesn't value users. He doesn't want to spend an extra hour or a month.
