import {DELETE,universalFilter} from '@rohitambawata9716/array-method-shortcuts'
This file includes two array filter methods:
1. DELETE method
2. universalFilter method
1. DELETE method usage
In short it is a filter method
Theory:This method is useful in those situations where we want to remove an item of the array(data provided by database or any data.js file holds an array of objects or simple array) whenever someone clicked on that item.
Example: const data = [{id:0,name:'dummy1'},{{id:1,name:'dummy2'}}] etc.
This dummy array holds 2 Objects.
Functional Component:
const [user,setUser] = useState(data)
const clicked = (id)=>{
setUser(DELETE(user,id)) //use a hook useState
//the above method will only delete the clicked div
}
}
return(){
data.map((item)=>{
return (
<div onClick={()=>clicked(item.id)}>
{item.name}
)
})
}
1. universalFilter method usage
Theory: This method is useful for universal filtering a given data by providing two arguments.
1. Data (array)
2. string of bool condition
Functional Component:
const [user,setUser] = useState(data)
const clicked = (id)=>{
// Exmp 1 setUser(universalFilter(user,'id !== id')) //use a hook useState
// Exmp 2 setUser(universalFilter(user,'name === "Rohit" ')) //use a hook useState
//the above method will only delete the clicked div
}
}
return(){
data.map((item)=>{
return (
<div onClick={()=>clicked(item.id)}>
{item.name}
)
})
}
