This is a modified version from underscore. https://github.com/jashkenas/underscore/blob/master/underscore.js
With some differences:
Similar to invariant but only logs a warning if the condition is not met. This can be used to log issues in development environments in critical paths. Removing the logging code for production environments will keep the same logic and follow the same code paths.

inlined Object.is polyfill to avoid requiring consumers ship their own https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is
Support style names that may come passed in prefixed by adding permutations of vendor prefixes.

Highlights all occurrences of search terms (searchText) within a string (textToHighlight). This function returns an array of strings and s (wrapping highlighted words).
Called immediately before mounting occurs, and before Component#render.
Avoid introducing any side-effects or subscriptions in this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
Called when the component may be receiving new props. React may call this even if props have not changed, so be sure to compare new and existing props if you only want to handle changes.
Calling Component#setState generally does not trigger this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
Called immediately before rendering when new props or state is received. Not called for the initial render.
Note: You cannot call Component#setState here.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
Catches exceptions generated in descendant components. Unhandled exceptions will cause the entire component tree to unmount.
Called immediately after a component is mounted. Setting state here will trigger re-rendering.
Called immediately after updating occurs. Not called for the initial render.
The snapshot is only present if getSnapshotBeforeUpdate is present and returns non-null.
Called immediately before mounting occurs, and before Component#render.
Avoid introducing any side-effects or subscriptions in this method.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
Called when the component may be receiving new props. React may call this even if props have not changed, so be sure to compare new and existing props if you only want to handle changes.
Calling Component#setState generally does not trigger this method.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
Called immediately before a component is destroyed. Perform any necessary cleanup in this method, such as
cancelled network requests, or cleaning up any DOM elements created in componentDidMount.
Called immediately before rendering when new props or state is received. Not called for the initial render.
Note: You cannot call Component#setState here.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
如果传入为数字，返回值也为数字 如果传入为 Date 的实例，返回值也为 Date 的实例 默认返回 format 格式的字符串
Runs before React applies the result of render to the document, and
returns an object to be given to componentDidUpdate. Useful for saving
things such as scroll position before render causes changes to it.
Note: the presence of getSnapshotBeforeUpdate prevents any of the deprecated lifecycle events from running.
Called to determine whether the change in props and state should trigger a re-render.
Component always returns true.
PureComponent implements a shallow comparison on props and state and returns true if any
props or states have changed.
If false is returned, Component#render, componentWillUpdate
and componentDidUpdate will not be called.
Register a resize event on Window
The event handler got a second parameter: {deltaX, deltaY}.
The onResize callback is throttled to run only once in a frame, you don't need to throttle the callback.

Hyphenates a camelcased CSS property name, for example:
hyphenateStyleName('backgroundColor') < "background-color" hyphenateStyleName('MozTransition') < "-moz-transition" hyphenateStyleName('msTransition') < "-ms-transition"
As Modernizr suggests (http://modernizr.com/docs/#prefixed), an ms prefix
is converted to -ms-.
Given a string or object, convert that input to RGB
Possible string inputs:
"red"
"#f00" or "f00"
"#ff0000" or "ff0000"
"#ff000000" or "ff000000"
"rgb 255 0 0" or "rgb (255, 0, 0)"
"rgb 1.0 0 0" or "rgb (1, 0, 0)"
"rgba (255, 0, 0, 1)" or "rgba 255, 0, 0, 1"
"rgba (1.0, 0, 0, 1)" or "rgba 1.0, 0, 0, 1"
"hsl(0, 100%, 50%)" or "hsl 0 100% 50%"
"hsla(0, 100%, 50%, 1)" or "hsla 0 100% 50%, 1"
"hsv(0, 100%, 100%)" or "hsv 0 100% 100%"判断一个校验函数是否是异步的，异步的校验函数必须使用 createAsyncValidator 创建

生成一个默认的onChange回调，这个回调会触发model.validate
如果不需要在onChange的时候触发校验，如下即可：
const onChange = useCallback(value => model.value = value, [model]);例如是一个input：
const onChange = useCallback((value: React.ChangeEvent<HTMLInputElement>) => {
model.value = e.target.value;
}, [model]);可以配合usePipe使用：
function mapEventToValue(e) {
return e.target.value;
}
function Foo() {
const onChange = FieldUtils.usePipe(
mapEventToValue,
FieldUtils.makeChangeHandler(model),
);

Parse a base-16 hex value into a base-10 integer
Attempts to parse the offset provided as a prop as a percentage. For
instance, if the component has been provided with the string "20%" as
a value of one of the offset props. If the value matches, then it returns
a numeric version of the prop. For instance, "20%" would become 0.2.
If str isn't a percentage, then undefined will be returned.

Called to determine whether the change in props and state should trigger a re-render.
Component always returns true.
PureComponent implements a shallow comparison on props and state and returns true if any

If false is returned, Component#render, componentWillUpdate
and componentDidUpdate will not be called.
