Similar to [`m.render()`](render.md), the `m.mount()` method takes a component and mounts a corresponding DOM tree into `element`. If `element` already has a DOM tree mounted via a previous `m.mount()` call, the component is diffed against the previous vnode tree and the existing DOM tree is modified only where needed to reflect the changes. Unchanged DOM nodes are not touched at all. Similar to [`m.render()`](render.md), the `m.mount()` method takes a component and mounts a corresponding DOM tree into `element`.

#### Replace a component
Running `mount(element, OtherComponent)` where `element` is a current mount point replaces the component previously mounted with `OtherComponent`.
#### Unmount
Using `m.mount(element, null)` on an element with a previously mounted component unmounts it and cleans up Mithril internal state. This can be useful to prevent memory leaks when removing the `root` node manually from the DOM.

### Performance considerations
It may seem wasteful to generate a vnode tree on every redraw, but as it turns out, creating and comparing Javascript data structures is surprisingly cheap compared to reading and modifying the DOM. It may seem wasteful to generate a vnode tree on every redraw, but as it turns out, creating and comparing Javascript data structures is surprisingly cheap compared to reading and modifying the DOM.
Touching the DOM can be extremely expensive for a couple of reasons. Alternating reads and writes can adversely affect performance by causing several browser repaints to occur in quick succession, whereas comparing virtual dom trees allows writes to be batched into a single repaint. Also, the performance characteristics of various DOM operations vary between implementations and can be difficult to learn and optimize for all browsers. For example, in some implementations, reading `childNodes.length` has a complexity of O(n); in some, reading `parentNode` causes a repaint, etc. Touching the DOM can be extremely expensive for a couple of reasons.

Unlike with `m.mount()` and `m.route()`, a vnode tree rendered via `m.render()` does not auto-redraw in response to view events, `m.redraw()` calls or `m.request()` calls.

### Retrieving response details
By default Mithril attempts to parse a response as JSON and returns `xhr.responseText`. It may be useful to inspect a server response in more detail, this can be accomplished by passing a custom `options.extract` function:
```javascript
m.request({
method: "GET",
url: "/api/v1/users",
extract: function(xhr) {return {status: xhr.status, body: xhr.responseText}}
})
.run(function(response) {
console.log(response.status, response.body)
})
```
The parameter to `options.extract` is the XMLHttpRequest object once its operation is completed, but before it has been passed to the resulting [stream](prop.md), so the stream may still end up in an errored state if processing throws an exception.

Many server-side frameworks provide a view engine that interpolates database data into a template before serving HTML (on page load or via AJAX) and then employ jQuery to handle user interactions.

## Passing vnodes to `m.mount()` and `m.route()`
In `v0.2.x`, `m.mount(element, component)` tolerated [vnodes](vnodes.md) as second arguments instead of [components](components.md) (even though it wasn't documented). Likewise, `m.route(element, defaultRoute, routes)` accepted vnodes as values in the `routes` object.
In `v1.x`, components are required instead in both cases.
### `v0.2.x`
```javascript
m.mount(element, m('i', 'hello'));
m.mount(element, m(Component, attrs));
m.route(element, '/', {
'/': m('b', 'bye')
})
```
### `v1.x`
```javascript
m.mount(element, {view: function () {return m('i', 'hello')}});
m.mount(element, {view: function () {return m(Component, attrs)}});
m.route(element, '/', {
'/': {view: function () {return m('b', 'bye')}}
})
```
## `m.route` mode ## `m.route` mode
`m.route.mode` was replaced by `m.route.prefix(prefix)` where `prefix` can be `#`, `?`, `` (for "pathname" mode). The new API also supports hashbang (`#!`), which is the default, and it supports non-root pathnames and arbitrary mode variations such as querybang (`?!`) `m.route.mode` was replaced by `m.route.prefix(prefix)` where `prefix` can be `#`, `?`, `` (for "pathname" mode).
