I’m not making any promises, but you can do this if you wish. I’m not telling you to use this tool. I am just suggesting that you get rid of your type annotations as soon as possible.
Type annotations are a pain. Especially when you have tons of them. And if you ever end up with a large type-full file (like mine), then you’ll feel like the words are crawling across your screen.
Type annotations in code are something that I see a lot of people struggle with. They’re an extremely distracting part of the code. There’s some kind of automatic way to insert them at the beginning of your file, but it’s not a nice way to start. The only way I can think of to fix this is by running `git rm –cached type-full.js` (the file is just a couple of hundred lines long).
Type annotations can be used in multiple places. In TypeScript, they can be used to set the default type of variable declarations, declaring local variables, and method overloading (so when you do something like `this.name = ‘Fred’` you can get the right type from your annotations).
Type annotations can also be useful when you are trying to change a variable to a private property. For example, declaring a variable that takes the global environment variable as a parameter can dramatically improve the type safety of the variable.
One thing that type annotations can’t do is change the type of an expression. An expression can only be assigned a type if the type is a reference or is an integer constant. So if you assign a function type to a variable, you would need to add parentheses to the beginning of the type or cast the variable to the correct type. However, you can do this with type annotations as well.
The problem is that in type annotations you can only have the type of an expression, not the variable.
Of course you can, but it only works for the expression that you’re annotating. An expression can be defined as a variable, function, or class, but you can only annotate a variable. An expression has both the type of the variable and the type of the expression. So you can annotate any variable, no matter what type it is.
By the way, you don’t have to type annotations if you don’t want to. You can just leave out the annotation.
