How to delete an object in an array in lodash

You can use lodash's remove function to achieve this. It transforms the array in place and return the elements that have been removed

var array = [{a: 1}, {a: 0}, {a: 9}, {a: 5}];
var removed = _.remove(array, item => item.a === 0);

console.log(array);
// => [{a: 1}, {a: 9}, {a: 5}]

console.log(removed);
// => [{a: 0}]

ES6

const arr = [{a: 1}, {a: 0}, {a: 9}, {a: 5}];

const newArr = _.filter(arr, ({a}) => a !== 0);

ES5

var arr = [{a: 1}, {a: 0}, {a: 9}, {a: 5}];

var newArr = _.filter(arr, function(item) { return item.a !== 0 });

Other then _.remove or _.filter you can also use reject()

var array = [{a: 1}, {a: 0}, {a: 9}, {a: 5}];
var result = _.reject(array , ({a}) => a===0 });

console.log(result);//[{a: 1}, {a: 9}, {a: 5}]

use this pass arr, key on which you want condition to apply and value is value of key you want to check.

function removeElem(arr,key,value){
    return arr.filter(elem=>elem[key]===value)
}
