how to use the overevery function from lodash in javascript

To use the _.overEvery function from lodash, you first need to install lodash in your project. You can do this using npm:

index.tsx
npm install lodash

Then, you can import the function into your code:

index.tsx
const _ = require('lodash');

const isEven = x => x % 2 === 0;
const isPositive = x => x > 0;

const isEvenAndPositive = _.overEvery([isEven, isPositive]);

console.log(isEvenAndPositive(6)); // true
console.log(isEvenAndPositive(-7)); // false
console.log(isEvenAndPositive(5)); // false

In the above example, we define two simple functions isEven and isPositive which check if a number is even and if it is positive, respectively. We then use _.overEvery to create a new function isEvenAndPositive which returns true only if both conditions are satisfied.

_.overEvery takes an array of functions and returns a new function. The new function, when called, will pass the arguments to each of the functions in the array, and will return true only if all the functions return true.
