How does lodash.over work?
lodash.over is a function that takes multiple functions as arguments and returns a new function that invokes each of the original functions with the same arguments, returning an array of their results.
For example, _.over(func1, func2)(value) is equivalent to [func1(value), func2(value)].
Ai Example
1 2 3const getMax = _.over(Math.max, (a, b) => b); console.log(getMax(1, 2)); // 2 console.log(getMax(2, 1)); // 1
In this example, getMax is a new function created by calling _.over with Math.max and an arrow function that returns the second argument (b). When getMax is called with two numbers, it first calls Math.max with the same arguments, then calls the arrow function with the same arguments and returns its result. In effect, getMax returns the maximum of two numbers, but if the two numbers are equal, it returns the second one.
