How to Bind All Methods of a Specific Name in an Object Using a Binding Map

How can I bind all methods of a certain name from an object into a template via a binding map?

const exampleObject = { methodOne() { console.log('method one'); }, methodTwo() { console.log('method two'); }, methodThree() { console.log('method one'); }};

Binding methods in JavaScript can be efficiently handled using a binding map, allowing you to dynamically associate object methods to a template based on their names. This technique is particularly useful in complex applications where method names need to correlate with UI elements or other components.

const bindingMap = {};

for (const [key, value] of Object.entries(exampleObject)) {
    if (key === 'methodOne') {
        bindingMap[key] = value.bind(exampleObject);
    }
}

const template = () => {
    bindingMap.methodOne(); // This will correctly call methodOne of exampleObject.
};

Causes

• Need for dynamic method binding.
• Majority of methods might share the same name.
• Template rendering requiring specific method functionality.

Solutions

• Create a binding map that associates the methods with the desired identifiers.
• Use Object.keys or Object.entries to filter and bind only those methods that match the specified name.
• Utilize template literals or function calls to ensure methods are invoked correctly within the template.

Mistake: Not binding methods in the correct scope.

Solution: Ensure that the context (instance of the object) is correctly bound using `.bind(this)` or by directly invoking the methods on their respective object.

Mistake: Omitting error handling for undefined methods.

Solution: Always check if the method exists in the object before binding or invoking it.
