JSDoc @type for list of declarations

[roncli]

Issue Type: Bug

When using the @type JSDoc for an empty array when declaring multiple variables, only the first declaration is recognized by intellisense. It is overridden by what is actually in the array.

It's possible I'm not documenting this correctly, so if that's the case please correct me.

Example of it working for the first declaration:

Example of it failing for other declarations:

Example code:

/** @type {string[]} */
const a =  [],
    /** @type {string[]} */ b= [];

a;
b;

a is string[].
b is any[]

One workaround is to use a type cast instead:

/** @type {string[]} */ const a =  [],
    b=  /** @type {string[]} */([]);
