Multiple javascript methods have the same name_how to call them

When developing JavaScript applications, you may encounter multiple methods with the same name. This situation is common when multiple people collaborate on development or reference multiple open source libraries. So what should you do when this happens? This article will introduce several solutions.

1. Modify the method name

This is the most intuitive solution. Modify the method name with the same name to make it unique in the same application. But this method is also the most troublesome solution, because if this method is referenced in many places, all places that reference this method need to be modified. This is not only time-consuming and labor-intensive, but also error-prone.

2. Using namespaces

In JavaScript, using namespaces can effectively solve the problem of multiple methods with the same name. A namespace is similar to a package, which contains multiple methods or objects under the same theme. The namespace is defined as follows:

<code>var myNamespace = {
    method1: function() {},
    method2: function() {},
    method3: function() {}
};</code>

We can use dot notation to call these methods, such as myNamespace.method1(). In this way, even if there are multiple methods with the same name, there will be no conflict.

3. Using closures

A closure is a combination of a function and its lexical environment, which can encapsulate some variables internally to avoid the pollution of global variables. In JavaScript, using closures can effectively solve the problem of multiple methods with the same name. For example:

<code>(function() {
    function myFunction() {},
    function myFunction() {}
    
    return {
        myFunction: myFunction
    };
})();</code>

In this example, we use the concepts of immediate execution functions and closures to wrap these two methods with the same name inside. We expose one of the methods so that we can call this method externally without conflict.

4. Using object literals

Object literals are a way to create objects in JavaScript and can be used to organize and manage methods with duplicate names. For example:

<code>var myObject = {
    myFunction: function() {},
    myFunction: function() {}
};</code>

We can use dot notation to call these methods, such as myObject.myFunction(). In this way, even if there are multiple methods with the same name, there will be no conflict.

Summary

When developing JavaScript applications, the problem of multiple methods with the same name is very common. We can effectively solve this problem by using various methods such as modifying method names, using namespaces, using closures, and using object literals. Which method to choose depends on the specific application scenario and development needs, and needs to be selected under specific circumstances.
