当代码没有任何问题时，VS 代码一直显示红色下划线

Question

my VS code keeps showing the red underline as if there's anything wrong with my code when I pasted or delete some console or comment, which is weird because the red underline is running all over the place. look at the image below to see what it looks like.

this error doesn't affect my code but it's annoying to see the red underline everywhere. i'm seeking for a solution, does anyone ever meet this error? and how to fix it?

Answer 1

This seldom occurs when your code has large trunks of unsaved changes. Just save your code once and you are good to go.
