               },
               "medium":{
                  "ext":".png",
                  "mime":"image/png",
                  "width":399,
                  "height":750,
                  "size":430.94,
                  "url":"/uploads/medium_video1.png"
               },
               "small":{
                  "ext":".png",
                  "mime":"image/png",
                  "width":266,
                  "height":500,
                  "size":230.47,
                  "url":"/uploads/small_video1.png"
               }
            },
            "ext":".mp4",
            "mime":"video/mp4",
            "url":"/uploads/video1.mp4",
         }
      ]
   }
]

some are images and some are videos

without videos this code works fine

async fetch() {
  const matchingAlbums = await this.$strapi.find('albums', {
    slug: this.$route.params.slug,
  })
  const images = []
  matchingAlbums[0].media.map((item) => {
    return images.push({
      thumb: `if mp4 then item.formats.large.url else item.url`
      width: item.width,
      height: item.height,
      src: item.url,
      mime: item.mime,
    })
  })

  this.album = matchingAlbums[0]
  this.images = images
},

but now that i have videos in my array, i need to change the thumb to the image path from item.formats.large.url where the mime is video/mp4

I tried doing if statement inside the map and push but it wont work.
I appreciate your help.

Answers:

Use a ternary expression.

thumb: item.mime == 'video/mp4' ? item.formats.large.url : item.url,
