JavaScript remove element from array if element includes specific string

Question

JavaScript remove element from array if element includes specific string

I have a collection of objects that share this structure

[{ id: "11", name: "Car", symbol: "CA" }
,{ id: "13", name: "Cycle", symbol: "CY" }
,{ id: "15", name: "Train", symbol: "TA" }
,{ id: "3", name: "Ufo", symbol: "UF" }]

Suppose I have the string Car, how can I search through the array of objects to identify which object, if any, contains that specific string in the name field and then remove that object from the array?

This is my current progress (Which is essentially nothing as I am unsure how to proceed)

function remove_obj_from_array_of_objs(str, array_of_objs){

}

Answer №1

To achieve this, you can utilize the filter() and includes() methods.

const information = [{ id: "11", name: "Car", symbol: "CA" },{ id: "13", name: "Cycle", symbol: "CY" },{ id: "15", name: "Train", symbol: "TA" },{ id: "3", name: "Ufo", symbol: "UF" }]

const outcome = information.filter(({name}) => !name.includes('Car'))
console.log(outcome)

Utilize Array's filter() method in this way:

var vehicleArr = [{ id: "11", name: "Car", symbol: "CA" }
,{ id: "13", name: "Cycle", symbol: "CY" }
,{ id: "15", name: "Train", symbol: "TA" }
,{ id: "3", name: "Ufo", symbol: "UF" }];

var notIncludesCar = vehicleArr.filter(item => !item.name.includes("Car"));

console.log(notIncludesCar);

console.log(notIncludesCar);

Utilize Array.filter in order to selectively remove elements from an array based on a specified condition.

_arr.filter( el => el.name!==_str);

var information = [{ id: "11", name: "Car", symbol: "CA" }
,{ id: "13", name: "Cycle", symbol: "CY" }
,{ id: "15", name: "Train", symbol: "TA" }
,{ id: "3", name: "Ufo", symbol: "UF" }]

function eliminate_array_element(_str, _arr){
  return  _arr.filter( el => el.name!==_str);
}

var response = eliminate_array_element("Car", information);
console.log(response);

To remove an item from an array of objects, start by iterating through the array and checking if the Key value matches your Search String. If a match is found, delete the object at that index from the array:

function removeFromArrayOfObjects(searchString, arrayOfObjects){
    for (var i=0; i < arrayOfObjects.length; i++) {
        if (arrayOfObjects[i].name === searchString) {
            arrayOfObjects.splice(i, 1);
        }
    }
}
