We can also perform various operations on the object like property adding, property removing, property editing, etc while looping through the array.

If you're unable to use the latest features of JavaScript, then perhaps you can rely on a simple for loop to check if a key in the object of arrays has a certain value. Using javascript we will loop through an array of objects in 5 different ways. For example:Ĭonsole.log(objs.some(() => name = 'John')) // output: true For example, if two objects contain the key value pair, type: 'apples', an output object should represent the value, in this case, 'apples', and the number of times it. In ES6+, we can destructure function arguments to simplify the syntax even more. I am trying to find all the objects that contain the same key value pair and create a new array of objects with the duplicate objects with the number of times they were found. We can use this to test if a key in the object of arrays has a certain value in the following way:Ĭonsole.log(objs.some((obj) => obj.name = 'John')) // output: true It tests whether at least one element in the array satisfies the test condition (which is implemented by the provided function). Introduced in ES5, the some() method returns a boolean value. sort () is a way to get the min value-form an array. Using the Math functions with the spread operator () and sorting the array numerically with. If we wanted to check if, for example, the name property with a specific value exists in the objects array, we could do it in the following ways: Use JavaScript reduce () or Math method to get the min value in an array of objects. Let's suppose we have an array of objects like the following:
