How can i filter array on object in javascript [duplicate]

Question

I have an array named files:

        files = [
            {
                id: "1", 
                title: "aras", 
                price: 100, 
                size: 25, 
                tools: [
                    "Hammer",
                    "Zip",
                    "Line",
                    "Nexti"
                    ]
            },
            {
                id: "2", 
                title: "yasio", 
                price: 150, 
                size: 30, 
                tools: [
                    "Hammer",
                    "Zip",
                    ]
            },
            {
                id: "3", 
                title: "janio", 
                price: 200, 
                size: 30, 
                tools: [
                    "Line",
                    "Nexti"
                    ]
            },
            {
                id: "4", 
                title: "chashio", 
                price: 400, 
                size: 35, 
                tools: [
                    "Nexti"
                    ]
            },



          ]

I want to filter this object, for example, to get the array: prices between 90 to 150 and sizes between 25 to 40 and tools to include Hammer and Zip. output must be:

{id: "1", title: "aras", price: 100, size: 25,tools:[...]},
{id: "2", title: "aras", price: 150, size: 30,tools:[...]},
{id: "4", title: "aras", price: 90,  size: 40,tools:[...]},

How can i do it?

files.filter(function(file){
            return ((file.price>= 90 && file.price<=150) && (file.size >= 25 && file.size <= 40))
    })

All you need to use Array.prototype.filter() to return items which satisfies the following condition:

(price>=90 && price <= 150) && (size >= 25 && size <= 40)

var files = [
  {id: "1", title: "aras", price: 100, size: 25, tools: ["Hammer","Zip","Line","Nexti"] },
  {id: "2", title: "aras", price: 150, size: 30, tools: ["Hammer","Zip"]},
  {id: "3", title: "aras", price: 160, size: 35, tools: ["Line","Nexti"]},
  {id: "4", title: "aras", price: 90,  size: 40, tools: ["Nexti"]},
  {id: "5", title: "aras", price: 200, size: 45, tools: []}
]

var res = files.filter(f => (f.price>=90 && f.price <= 150) 
                         && (f.size >= 25 && f.size <= 40) 
                         && (f.tools.includes('Hammer') &&  f.tools.includes('Zip')));

console.log(res);

thanks for your answer, my problem is here, I can't filter by tools in my files. do you have some idea for it?

Mamun Over a year ago

@Aras, filter() is a native JavaScript array method...I don't know why you can't use that!

Aras Over a year ago

I use it I want to check some object in my arras list something like includes methods

Mamun Over a year ago

@Aras, do you want both Hammer and Zip to be present in the tools?....updated the answer with includes.......please check.
