Overview of this book

Built on the Salesforce App Cloud, the new Salesforce Lightning Experience combines three major components: Lightning Design System, Lightning App Builder, and Lightning Components, to provide an enhanced user experience. This book will enable you to quickly create modern, enterprise apps with Lightning Component Framework. You will start by building simple Lightning Components and understanding the Lightning Components architecture. The chapters cover the basics of Lightning Component Framework semantics and syntax, the security features provided by Locker Service, and use of third-party libraries inside Lightning Components. The later chapters focus on debugging, performance tuning, testing using Lightning Testing Services, and how to publish Lightning Components on Salesforce AppExchange.

Avoiding nested aura:if in aura:iteration


To understand this scenario, let's take an example component code. Let's name the component ifElseLadder. The component displays numbers in a nested manner.

The component code is as follows:

<aura:component >

<aura:iteration items="1,2,3,4,5" var="item">
    <aura:if isTrue="{!v.truthy}">
        True 
        <aura:set attribute="else">
          <aura:iteration items="{!v.arraySize}" var="i">
            <aura:if isTrue="{!v.innerCmpDisplay}">
                <div>
                    {!i}
                </div>
                <aura:iteration items="{!v.arraySize}" var="j">
