Methods vs Computed in Vue ?

What are Methods?

Methods in Vue.js are simple JavaScript functions defined within the methods object of a Vue component. They are called directly from the template or within other methods using this keyword. Methods are suitable for performing actions, such as event handling, form submissions, or any other imperative logic.

Syntax:

export default {
    data() {
        return {
            // data properties
        };
    },
    methods: {
        methodName() {
            // method logic
        }
    }
}

Benefits of Using Methods

• Methods provide a clear and explicit way to define behavior within Vue components.
• They are reusable and can be called from multiple places within the component.
• Methods can accept parameters, allowing for dynamic behavior based on input.

What are Computed Properties?

Computed properties in Vue.js are functions that are defined within the computed object of a Vue component. They are reactive and automatically re-evaluate whenever their dependent data properties change. Computed properties are suitable for deriving and caching computed values based on reactive data.

Syntax:

export default {
    data() {
        return {
            // data properties
        };
    },
    computed: {
        propertyName() {
            // computed property logic
        }
    }

Benefits of Using Computed Properties

• Computed properties offer a clean and concise way to derive values from existing data.
• They automatically cache their result and only re-compute when their dependencies change, improving performance.
• Computed properties promote code readability and maintainability by separating derived data from other logic.
