* Binds methods of an object to the object itself, overwriting the existing method.

|
* Method names may be specified as individual arguments or as arrays of method names.

|
*
|

|
* @template T - The type of the object.
|
||
|
|
* @param {T} object - The object to bind methods to.
|

|
|
* @param {Array<Many<string>>} [methodNames] - The method names to bind, specified individually or in arrays.
|
||
|
|
* @returns {T} - Returns the object.
|
||
|
|
*
|

|
|
* @example
|

|
|
* const view = {
