If else to set a new variable in edge template

[dmeinke-etc]

What's the best way to set a variable in an edge template with an if else. I want to pad a number to double digits from a preexisting array. This is what I have and it seems to not process the first @set

@if(numDate == 1 || numDate == 2 || numDate == 3 || numDate == 4 || numDate == 5 || numDate == 6 || numDate == 7 || numDate == 8 || numDate == 9 ) @set('numDateCalc', '0'+numDate) @else @set('numDateCalc', numDate) @end
I know the best way is to somehow make this array in the controller and I always have previously this is just a different case.

Can I call a function from somewhere to pad the number?

I tend to use ternaries for simple if/else checks.

@set('numDateCalc', numDate < 10 ? `0${numDate}` : `${numDate}`)

You can also create a preload file and add global EdgeJS helpers there, I usually call mine globals

node ace make:prldfile globals

// start/globals.ts

import View from '@ioc:Adonis/Core/View'

View.global('padDate', (numDate: number) => {
  if (numDate > 9) return `${numDate}`

  return `0${numDate}`
})

<!-- some view -->

<p>{{ padDate(numDate) }}</p>

I also have a lesson that goes into a little more detail on this as well:
