how to use the negate function from lodash in javascript

The negate function from lodash is a utility function that returns a new function that negates the result of the given predicate function. The predicate function is called with the same arguments that are passed to the new function.

Here's an example of how to use negate:

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

// Define a predicate function that checks if a number is even
const isEven = num => num % 2 === 0;

// Define a function that uses negate to create a new function that checks if a number is odd
const isOdd = _.negate(isEven);

console.log(isOdd(1)); // true
console.log(isOdd(2)); // false

In this example, we define a predicate function isEven which checks if a number is even. We then use the negate function to create a new function isOdd that negates the result of isEven. We can pass any number to isOdd and it will return the opposite of isEven, effectively checking if the number is odd.

Note that negate returns a new function, so you should assign the result to a variable if you want to use it later.
