Lodash is a JavaScript library that provides utility functions for common programming tasks. It can be used to set values in JavaScript in a few different ways.
- Using the
_.set()
function:
let obj = {
name: 'John'
};
_.set(obj, 'age', 24);
console.log(obj);
// { name: 'John', age: 24 }
The _.set()
function takes two arguments: an object and a path, and sets the value of the path to the given value. In the example above, we set the age
property of the obj
object to 24
.
- Using the
_.assign()
function:
let obj = {
name: 'John'
};
_.assign(obj, { age: 24 });
console.log(obj);
// { name: 'John', age: 24 }
The _.assign()
function takes two arguments: an object and a source object, and assigns the properties of the source object to the given object. In the example above, we assign the age
property of the obj
object to 24
.
- Using the spread operator:
let obj = {
name: 'John'
};
obj = { ...obj, age: 24 };
console.log(obj);
// { name: 'John', age: 24 }
The spread operator can be used to spread the properties of an object into another object. In the example above, we spread the properties of the obj
object into a new object, and set the age
property to 24
.
