I have a component which has a list of teams over which the aura:iteration is looping.
I want to use the placeholder attribute of lightning:input as such:
<aura:iteration items="!v.dToPart.teams" var="eachTeam" indexVar="index">
<div class="slds-col slds-size_4-of-12 " >
<lightning:input placeholder="'Name of team '+ #index+1" aura:id="dToPart" value="!eachTeam.name" required="true"/>
</div>
</aura:iteration>
But this gives the following result:
This works perfectly fine, if i only include the index in the merge expression:
<aura:iteration items="!v.dToPart.teams" var="eachTeam" indexVar="index">
<div class="slds-col slds-size_4-of-12 " >
<lightning:input placeholder="'Name of team '+ #index+1" aura:id="dToPart" value="!eachTeam.name" required="true"/>
</div>
</aura:iteration>
Can someone please help me out?

Expressions need to start with # or ! to be recognized:
<lightning:input placeholder="#'Name of team '+ (index+1)" ... />
Note that the inner ( and ) are necessary to treat the index + 1 as arithmetic instead of string concatenation.
An expression is always in the form of , followed by # or !, followed by the expression to be evaluated, and finally ending in .
