Answer 1

Without more info vscode can't know that the parameter within your function must be a string. If you use JSDoc comments to indicate that you'll get the intellisense you expect.

/**
 * @param {string} word 
 */
function qweqwe(word) {
  const word = word.   // string intellisense here
}

In your second example:

const word = "mom";
const werwer = word.

vscode can do a good job of predicting the type of word from the previous assignment.
