# ✨ useState
useState
is a function that allows you to have state variables in functional components. You pass the initial state to this function and it returns a variable with the current state value (not necessarily the initial state) and another function to update this value.
# 🍁 Usage
The useState
function is used as the following reactive state:
import { useState } from 'vue-composable-utils';
const [count, setCount] = useState();
import { useState } from "vue-composable-utils"
function Example() { // Declare a new state variable, which we'll call count
const [count, setCount] = useState(0);
We declare a state variable called count , and set it to 0 .
