Is there anyway to tell if a type a global/built-in type

[awareness481]

interface Array<T> {
    x: any;
}

For example here, is there any way to tell that Array<T> is not a new type but this is a declaration merge because Array<T> already exists from the builtin types?

You can use env.get_global_type.

Example:

stc/crates/stc_ts_file_analyzer/src/analyzer/expr/mod.rs

Line 1072 in 32d80ed

let obj = self.env.get_global_type(span, &js_word!("Function"))?;
