How Can I Filter a JavaScript Object Array Based on Multiple Attributes?

Filtering Object Array Based on Attributes

To filter a given array of objects based on specific attributes, you can utilize the Array.prototype.filter method in JavaScript. This powerful method allows you to create a new array containing only the elements that meet your specified criteria.

For instance, you have an array of real estate home objects and want to return a subset of homes based on their price, square footage, number of beds, and number of baths.

To achieve this, you can use the filter method as follows:

var newArray = homes.filter(function (el) {
  return el.price <= 1000 &&
         el.sqft >= 500 &&
         el.num_of_beds >= 2 &&
         el.num_of_baths >= 2.5;
});

In this example:

• The filter method iterates over each object in the 'homes' array.
• For each object, it checks if all of the criteria are met using the specified logical operators (&&).
• If an object meets all the conditions, it is included in the 'newArray'.

You can modify the criteria to filter based on your specific requirements. For example, to find homes with a price under $1000, square footage over 500, at least two beds, and at least 1.5 baths, you would use the following criteria:

el.price <= 1000 &&
el.sqft >= 500 &&
el.num_of_beds >= 2 &&
el.num_of_baths >= 1.5;

This code will filter the 'homes' array and return only the objects that satisfy these criteria, creating a new array with the filtered results.
