JS Filter Array in Array using Array - (Tags)

1

Hello, I’m trying to make a filterable list.

The data structure is like so:

data = [
{name: ‘john’, position: ‘developer’, languages: [‘python’, ‘ruby’, ‘html’},
{name: ‘jane’, position: ‘sales’, languages: [‘python’, ‘ruby’, ‘html’},
{etc}
]

filterLanguage = [‘python’, ‘ruby’, ‘etc’]

I’m trying to filter the main data list languages based on the filters selected in the second array ‘filterLanguage’.

I feel like i’ve been going around and around for hours on this.

I’ve tried various combinations of .filter(), .includes(), .some(), .every(), .indexOf(). etc. I feel like I’m just missing something.

Any help would be greatly appreciated! Thank you :smiley:

I was actually able to get it to work after I posted this.

Here’s the solution that I used:

const filterList = () => {

  return data.filter(job => {    

    return job.languages.some(tag => {

      return filterLanguage.includes(tag);

    })

  })

}

I’ll leave this here in case anyone needs something similar. It turns out I was just missing a return and I needed to normalize the data (ie. toLowerCase()) :smiley:
