Get filtered array by some with multiple conditions

Question

This is the structure of my arrays:-

projects array:-

let projects = [
    {
        id: 1,
        name: 'Project 1',
        techs: [
            id: 1
            name: 'Tech 1'
        ]
    },
    {
        id: 2,
        name: 'Project 2',
        techs: [
            id: 1
            name: 'Tech 2'
        ]
    },
    {
        id: 3,
        name: 'Project 3',
        techs: [
            id: 1
            name: 'Tech 3'
        ]
    },
    {
        id: 4,
        name: 'Project 4',
        techs: [
            id: 1
            name: 'Tech 1'
        ]
    }
]

Right now I'm able to get only filtered projects of just Tech 1 as shown below:-

let filteredProjs = projects.filter(proj => proj.techs.some(tech => tech.name === 'Tech 1'))

I want to get filtered projects of Tech name = 'Tech 1' & 'Tech 2'. But it return me nothing when I did as shown below:-

let filteredProjs = projects.filter(proj => proj.techs.some(tech => tech.name === 'Tech 1' && tech.name === 'Tech 2'))

How can I do this?

Answer 1

You might need to try OR operator (||) instead of AND (&&).

In Computer Programming, AND returns true only when conditions on both the sides evaluates to true. In case of OR, it evaluates to true if either of the conditions on any side returns true.

In your case I assume you want to filter out projects in which Tech name equals 'Tech 1' OR 'Tech 2'.
