  })
}

// JSON parsing.
const variables = JSON.parse(rawData)
  .filter(isDuplicate)
  .map(mapProgram({ language: global.language, idChannel }))
}

after.js

const variables = []

// JSON parsing.
const variables = JSON.parse(rawData)
  .filter((program, i, array) => {
   return array.slice(i+1).contains(p => {
     return p.program.genrePressCode !== program.program.genrePresseCode 
   }) 
  })
  .map(program => {
    return {
      url: `/${global.language}/channel/${idChannel}/show/${program.program.genrePresseCode}`,
      label: program.program.genrePresse,
      image: program.program.imageUrl
    }
  })
}

before.js

const variables = []

// JSON parsing.
for (const program of JSON.parse(rawData).programs) {
  if (temp.indexOf(program.program.genrePresseCode) == -1) {
    variables.push({
      url: `/${global.language}/channel/${idChannel}/show/${program.program.genrePresseCode}`,
      label: program.program.genrePresse,
      image: program.program.imageUrl
    })
  }
}

La fonction contains() n'existe pas de base, elle appartient à quel package ?

Voici la solution :

const variables = JSON.parse(rawData).programs
  .filter(program => program.program.genrePresseCode === parseInt(showId, 10))
  .map((program) => {
    if (program.video) {
      programTitle = program.program.genrePresse

      return {
        url: join(showId, 'video', `${program.video.programId}%2F${program.video.kind}`),
        label: `${program.video.title} <span class="h6">[${Math.floor((parseInt(program.video.durationSeconds, 10) / 60))} min]</span>`,
        image: program.video.imageUrl,
        }
      }
    })
