I have two array of objects
array1=[{name:'apple',deleted:false},
{name:'road',deleted:false},
{name:'tree',deleted:false}]
and
array2=[{name:'apple'},
{name:'tree'}]
what I want is : if array1 object has same names in array2, I want to change value of "deleted" in array1 to true . eg : {name:'apple',deleted:true}
expecting resulting array1:
array1=[{name:'apple',deleted:true},
{name:'road',deleted:false},
{name:'tree',deleted:true}]
here you can see , only apple, tree has deleted=true, because array2 has only 2 names : apple and tree.
you can :
loop on array1 with forEach for sample
use some function to set deleted boolean
deleted = array2.some(elem2 => elem2.name === elem.name)
const array1 = [{
name: 'apple',
deleted: false
},
{
name: 'road',
deleted: false
},
{
name: 'tree',
deleted: false
}
]
const array2 = [{
name: 'apple'
},
{
name: 'tree'
}
];
array1.forEach(elem => elem.deleted = array2.some(elem2 => elem2.name === elem.name));
console.log(array1);Use forEach() to loop array1 and use include() to set value of deleted
const array1=[{name:'apple',deleted:false},
{name:'road',deleted:false},
{name:'tree',deleted:false}]
const array2=[{name:'apple'},
{name:'tree'}]
array1.forEach(el=> el.deleted = array2.map(foo => foo.name).includes(el.name))
console.log(array1)const
items = [{ name: "apple", deleted: false }, { name: "road", deleted: false }, { name: "tree", deleted: false }],
deletedItems = [{ name: "apple" }, { name: "tree" }],
deletedSet = new Set(deletedItems.map((d) => d.name)),
updatedItems = items.map((i) => (deletedSet.has(i.name) ? { ...i, deleted: true } : i));
console.log(updatedItems);
