Lightning - sObject Initialization

sObject Initialization

When you are initializing sObject like below

<aura:attribute name="acc" type="Account" /> --> This is like Account acc; There is no memory allocation happened
hence while entering values we will get null issue. 

"TypeError: d is null
throws at https://domain.lightning.force.com/auraFW/javascript/5fuxCiO1mNHGdvJphU5ELQ/aura_prod.js:544:409"

Correct way of initializing is 

<aura:attribute name="acc" type="Account" default="{sObjectType:'Account'}"/> 
Account acc= new Accout(); equivalent. 



Component
************************************************************************************
<aura:component >
    <aura:attribute name="acc" type="Account" default="{sObjectType:'Account'}"/>
    <lightning:card iconName="standard:account">
    	<aura:set attribute="actions">
            <lightning:button  label="submit" onclick="{!c.submit}" />
        </aura:set>
        <aura:set attribute="title">
            sObject<br/>
            Account
        </aura:set>
        <lightning:input label="Account Name" value="{!v.acc.Name}"/> 
        <lightning:input label="Account Type" value="{!v.acc.type}"/> 
        <lightning:input label="Account Industry" value="{!v.acc.industry}"/> 
    </lightning:card>
</aura:component>
