Returns a new instance of this Record type with all values set to their default values.
Returns a new instance of this Record type with the value for the specific key set to its default value.
Returns the value associated with the provided key, which may be the default value defined when creating the Record factory function.
If the requested key is not defined by this Record type, then notSetValue will be returned if provided. Note that this scenario would produce an error when using Flow or TypeScript.

Deeply converts this Record to equivalent native JavaScript Object.
Note: This method may not be overridden. Objects with custom serialization to plain JS may override toJSON() instead.

Unlike other types in Immutable.js, the Record()
function creates a new
Record Factory, which is a function that creates Record instances.
See above for examples of using Record()
.
Note: Record
is a factory function and not a class, and does not use the
new
keyword during construction.
Records allow passing a second parameter to supply a descriptive name that appears when converting a Record to a string or in any error messages. A descriptive name for any record can be accessed by using this method. If one was not provided, the string "Record" is returned.
const { Record } = require('immutable')
const Person = Record({
name: null
}, 'Person')
var me = Person({ name: 'My Name' })
me.toString() // "Person { "name": "My Name" }"
Record.getDescriptiveName(me) // "Person"
True if maybeRecord
is an instance of a Record.
Radial Gradient fill style.
Instances of RadialGradientFill are immutable, meaning that its setters don't modify the object, but instead return a completely new modified object.
