In Vue.js, the watch property allows you to perform custom logic in response to changes in data properties, computed properties, or other reactive values. It provides a way to observe changes and react to them i
What is the purpose of the 'v-slot' directive in Vue.js? What is Vuex used for in a Vue.js application? How can you pass data from a parent to a child component in Vue.js? In Vue.js, what is the role of the 'watch' property? What is the purpose of the 'computed' pro...
Vue Router is the official router for Vue.js, providing navigation and routing capabilities for single-page applications (SPAs). Computed Properties: Vue.js allows the creation of computed properties, which are derived from the reactive data model. Computed properties are updated automatically when th...
In this example, computedClasses dynamically calculates the classes to be applied, and computedStyles calculates the inline styles based on component data. By using these techniques, you can dynamically apply CSS classes and inline styles in your Vue.js components based on changing data or component...
Here is an example to illustrate the functionality of the immediate property of watch in Vue: Let's assume that there is an array where each element is an object and each object has the following properties: name, age and gender. We want to monitor the age of all objects in the array ...
a computed property will only trigger effects when its computed value has changed from the previous one. But in the case of a computed that return new objects, Vue thinks that the previous and current values are different. If you want to avoid triggering effects in that case, you can compar...
In Vue.js we’re using v-model for two-way binding. The most popular way to use it is of course the form elements. In Vue 2, we can use only one v-model in a single component, but Vue 3 allows us to pass multiple v-models to our components by specifying their names. Let’s ...
Next, we used a computed property named totalprice to iterate over the cart array, multiply the item’s price by its quantity, and provide a total cost of the items in the cart. Every time a change is implemented in the cart, this property computes the total price and updates it in re...
Use a computed property once you need to deal with mutating a property that depends upon other data properties. Any changings to properties will execute the logic or the computed property. they’re stored depending on their conditions so they will possibly rerun if any dependency changes. ...
Let’s say we want to add a computed property that calculates the tax and total price of a product. How would we accomplish it? In Vue 2, you can do so by adding a computed field to the options object and then defining the property as shown in the code below: ...
