{country}                     field value
{row.status}                  current table row
{panel.index}                 current dynamic-panel entry index
{parentIndex}                 index in the surrounding repeater
{__variables.route.id}        variable (route param)
{__external.userRole}         host-app context
{myTabs.selectedTab}          active tab name
{flow.selectedStepIndex}      active step index

Quick patterns

{country} == "US"
isEmpty({companyCode})
notEmpty({email}) && notEmpty({phone})
contains({roles}, "admin")
containsAny({roles}, ["admin", "manager"])
toNumber({price}) * toNumber({quantity})
len({selectedItems}) > 0
inRange({age}, 18, 65)

If / else (ternary)

{isCompany} ? {companyCode} : {personalCode}
{country} == "US" ? "Domestic" : "International"
toNumber({quantity}) > 0 ? toNumber({sum}) / toNumber({quantity}) : 0

Nested:

{status} == "approved" ? ({isVip} ? "Priority" : "Standard") : "Draft"
contains({roles}, "admin") ? "Full access"
  : (contains({roles}, "editor") ? "Editing" : "Read only")

Arrays & aggregation

sumInArray({orderLines}, "amount")
countInArray({employees}, "id")
contains(collectValuesFrom({employees}, "role", true), "manager")
joinInArray({tags}, "name", ", ")

Dates

=today()                                     default value: today
addDays(today(), 14)                         two weeks from now
dateDiffDays({startDate}, {endDate}) >= 1    end after start
isWeekend({deliveryDate})                    weekend check

Row & panel context

row.status == "active"
toNumber(panel.amount) > 1000
{el1[parentIndex].country} == "US"

Template placeholders

Inside option templates, card templates, and dynamic text (double braces):

{{label}}   {{value}}   {{index}}   {{selected}}
{{ item.name }}   {{ item.status }}
@if (item.status == "Active") {<span>{{ item.status }}</span>}

Debug

dbg({clientType}, "clientType")     log to console, value passes through
