React & Modern Frontend (445 Qs)•Part 11: Legacy Architecture, Migration Patterns & Historical Internals (354 - 445)
What is the recommended approach of removing an array element in React state?
The better approach is to use Array.prototype.filter() method.
rust
For example, let's create a `removeItem()` method for updating the state.
javascript
removeItem(index) {
this.setState({
data: this.state.data.filter((item, i) => i !== index)
})
}
