How to convert a string to a boolean value in JavaScript correctly?

Hello everyone! I'm just starting to learn JavaScript and ran into a problem. I have a string that comes from the server or from a form. It can be `"true"` or `"false"`. I need to convert it into an actual boolean value `true` or `false` to use in conditions. I tried this code: ```javascript let str = "false"; let bool = Boolean(str); console.log(bool); // outputs true ``` But `Boolean("false")` returns `true`! This confuses me. I thought the string `"false"` should become `false`. I also tried double negation: ```javascript let str = "false"; let bool = !!str; console.log(bool); // also true ``` And that doesn't work either. I understand that an empty string `""` gives `false`, and any non-empty string gives `true`. But I need the string `"false"
