Overview of this book

<p>Vue.js is a library to build interactive web interfaces. The aim is to provide the benefits of reactive data binding and composable view components with an API that is as simple as possible.</p> <p>This book will teach you how to efficiently implement Vue.js in your projects. It starts with the fundamentals of Vue.js to building large-scale applications. You will find out what components, filters, methods, and computed properties are and how to use them to build robust applications.</p> <p>Further on, you will become familiar with ES6, single file components, module bundlers, and workflow automation. The best way to learn to code is to write it, so there’s an exercise at the end of most of the chapters for you to solve and actually test yourself on what you have learned. You can solve these in order to gain a better understanding of Vue.js.</p> <p>By the end of this book, you will be able to create fast front-end applications and increase the performance of your existing projects with Vue.js integration.</p>

v-for


In order to loop through each item in an array, we will use the v-for Vue's directive.

The v-for loop works on arrays/objects and is used to loop through each item in an array. This directive requires a special syntax in the form of item in array where array is the source data array and item is an alias for the array element being iterated on.

Note

If you are coming from the PHP world you may notice that v-for is similar to PHP's foreach function. But be careful if you are used to foreach($array as $value).

Vue's v-for is exactly the opposite, value in array. The singular first, the plural next.

Range v-for

Directive v-for can also take an integer. Whenever a number is passed instead of an array/object, the template will be repeated as many times as the number given:
