The arguments for both methods are the same, allowing you to pass a customized serializable `state` object as the first argument, a customized `title` (although most browsers will ignore this parameter) and the `URL` you want to add/replace in the browser's history. Bear in mind that **the History API only allows same-origin URLs**, so you cannot navigate to an entirely different website.

MD013 - Line length

Tags: line_length

Aliases: line-length Parameters: linelength, codeblocks, tables (number; default 80, boolean; default true)

This rule is triggered when there are lines that are longer than the configured line length (default: 80 characters). To fix this, split the line up into multiple lines.

This rule has an exception where there is no whitespace beyond the configured line length. This allows you to still include items such as long URLs without being forced to break them in the middle.

You also have the option to exclude this rule for code blocks and tables. To do this, set the code_blocks and/or tables parameters to false.

Code blocks are included in this rule by default since it is often a requirement for document readability, and tentatively compatible with code rules. Still, some languages do not lend themselves to short lines.

The older [Location API](https://developer.mozilla.org/en-US/docs/Web/API/Location) is not the best tool for the job. It **reloads the page**, but still allows you to modify the current URL and might be useful when working with **legacy browsers**. You can modify the URL, using either `Window.location.href`, `location.assign()` or `location.replace()`:

Surely, this dealt with encoding, but the multiline string has sneaked a newline character (`\n`) into the URL. This is because template literals preserve whitespace, leading to such issues. Breaking the string into multiple lines and concatenating them can help, but the code is starting to get ugly.

Admittedly, using the `URL` object can be a bit more verbose, but it's a worthwhile tradeoff. The code is much more readable and maintainable, and it's less prone to errors. Query parameters are now encoded properly, and delimiters are added automatically.

But that's not all. Having separated the base characters from the diacritical marks, you can then use `String.prototype.replace()` to **remove diacritical marks** from the string. This can be done by using a **regular expression** to match the diacritical marks in the given Unicode range (`u0300` to `u036f`) and replacing them with empty strings.

It's essential to note that only declarations are hoisted, while initializations are not. This means that if you declare and initialize a variable after using it, its value will not be initialized. However, this is a simplified explanation, so let's take a look at the various scenarios:

Turns out the `handler` is itself just an object. Apart from `handler.constructor()`, we can use the handler to store the unique instance of the class we want and if it has been instantiated. In doing so, we can create a handler object that can be reused for any class we want to convert into a singleton, while also allowing us to provide additional traps for any other operations we might want to customize.

The first step in modeling any sort of monetary value is to have a **structure for currency**. Luckily, `Intl` has this problem solved for us. You can use `Intl.NumberFormat` with `style: 'currency'` to get a **formatter** for a specific currency. This formatter can then be used to format a number into a currency string.
