How to remove multiple elements from array in JavaScript?
To remove multiple elements from array in JavaScript, we can use the array filter method.
For instance, we write
let valuesArr = ["v1", "v2", "v3", "v4", "v5"];
const removeValFrom = [0, 2, 4];
valuesArr = valuesArr.filter((value, index) => {
return removeValFrom.indexOf(index) === -1;
});
to call valueArr.filter with a callback that checks if the index of the element in valuesArr is in the removeValFrom array which has the indexes of the items in valuesArr that we want to remove.
A new array with the items that we want to keep are included, so we assign the array back to valuesArr.
Conclusion
To remove multiple elements from array in JavaScript, we can use the array filter method.
