DataBinder Class Constructor: constructor() Description: Initializes a new instance of the DataBinder class and sets up the internal state for storing bindings.

Parameters:

None. Returns:

A new instance of the DataBinder class. _ensureArray(input) Description: Ensures that the input is returned as an array. If the input is already an array, it is returned unchanged. If not, it is wrapped in an array.

Parameters:

input (any): The input value to be checked. Returns:

Array: An array containing the input value. _updateElement(target, value) Description: Updates the content of an HTML element based on its tag name. It handles multiple HTML tags such as DIV, SPAN, INPUT, LI, and P. If the target is of a different type, a warning is logged.

Parameters:

target (HTMLElement): The HTML element to update. value (string): The value to update the target element with. Returns:

None. bindOneWay({ source, target, propName = null }) Description: Creates a one-way binding between a source object and a target element. Any change in the source object automatically updates the target elements.

Parameters:

source (object): The source object to bind from. Must be a non-null object. target (HTMLElement | array): The target element(s) to bind to. This can be a single element or an array of elements. propName (string | null, optional): The property name in the target element to bind to. If not specified, the entire object is bound to the target. Returns:

Proxy: A proxy object for the source to enable tracking of changes. Throws:

TypeError: If the source is not an object or is null, or if any target is not a valid HTML element or object. bindTwoWay(inputs, outputs) Description: Creates a two-way binding between input and output elements. Changes made in one will automatically update the other.

Parameters:

inputs (HTMLElement | array): The input elements to bind. Can be a single element or an array of elements. outputs (HTMLElement | array): The output elements to bind to. Can be a single element or an array of elements. Returns:

None. updateValue(variableName, newValue) Description: Manually updates the value of a bound variable. If the variable is found in the bindings, it updates the value and triggers an update for the associated elements.

Parameters:

variableName (string): The name of the variable to update. newValue (any): The new value to assign to the variable. Returns:

None. trigger(variableName) Description: Manually triggers an update for a bound variable. This forces the associated elements to reflect the current value of the variable.

Parameters:

variableName (string): The name of the variable to trigger an update for. Returns:

None. Example Usage javascript Copier Modifier import DataBinder from 'databinder';

// Create an instance of DataBinder const binder = new DataBinder();

// One-Way Binding const dataState = { value: "Loading..." }; const display = document.getElementById('data-display');

binder.bindOneWay({ source: dataState, target: [display] });

// Two-Way Binding const usernameInput = document.getElementById('username'); const preview = document.getElementById('preview-username');

binder.bindTwoWay([usernameInput], [preview]);

// Updating a variable binder.updateValue('username', 'JohnDoe');

// Manually triggering an update binder.trigger('username');
