Accessing a specific attribute of an object contained within an array

Currently, I am utilizing Vue.js in my project and have implemented a method that involves comparing values from two different arrays.


array1:  [{ name: 'test1', somevar: true }, { name: 'test2', somevar: false }]
array2: ['test1', 'test3']

compare() {
    // In this section, my objective is to access an object property within array1
    this.array1.forEach((element) => {
      if(this.array1.element.name.includes(this.array2[0])) {
        // Upon validation, I aim to remove the compared value from array 1
        if(this.array2[0] !== -1) {
          var index = this.array1.element.name.indexOf(this.array2[0])
          this.array1.splice(index, 1)
        }
      }

I have identified a potential issue with this.array1.forEach((element). How can I effectively access the properties of that specific object?

Answer №1

array1 is actually an array, not an object. Therefore, trying to access this.array1.element will not yield the desired result. Instead, simply reference the element as the parameter provided to forEach.

In addition, the function passed to forEach accepts another argument: the second argument specifies the current element's index, eliminating the need to use indexOf.

Furthermore, instead of those adjustments, utilizing filter would be more suitable in this scenario:

const obj = {
  array1:  [{ name: 'test1', somevar: true }, { name: 'test2', somevar: false }],
  array2: ['test1', 'test3'],
  compare() {
    obj.array1 = obj.array1.filter(({ name }) => (
      !obj.array2.includes(name)
    ))
  }
}
obj.compare();
console.log(obj.array1);
