How does ramda.reject work?
ramda.reject is a function in the Ramda library that returns a new list with all the elements that satisfy a predicate function removed. The function takes two arguments: a predicate function and a list of values. The predicate function takes a single value and returns a Boolean value indicating whether that value should be removed from the resulting list. When ramda.reject is called, it applies the predicate function to each element in the input list. If the predicate function returns true for an element, that element is removed from the resulting list. If the predicate function returns false for an element, that element is included in the resulting list. For example, the following code uses ramda.reject to remove all even numbers from a list of integers: javascript Copy code {{{{{{{ const R = require('ramda'); const numbers = [1, 2, 3, 4, 5, 6]; const odds = R.reject((n) => n % 2 === 0, numbers); console.log(odds); // Output: [ 1, 3, 5 ] In this example, we use ramda.reject to create a new list odds that contains only the odd numbers from the input list numbers. The function applies the predicate function (n) => n % 2 === 0 to each element in numbers. For even numbers, the predicate function returns true, and those elements are removed from the resulting list. For odd numbers, the predicate function returns false, and those elements are included in the resulting list. Overall, ramda.reject is a useful utility function for creating a new list with elements removed based on a specified predicate function.

Ai Example

const R = require("ramda"); const students = [ { name: "Alice", grade: "A" }, { name: "Bob", grade: "B" }, { name: "Charlie", grade: "C" }, { name: "David", grade: "D" }, ]; const passingStudents = R.reject((student) => student.grade === "D", students); console.log(passingStudents); // Output: [ { name: 'Alice', grade: 'A' }, { name: 'Bob', grade: 'B' }, { name: 'Charlie', grade: 'C' } ]
In this example, we use ramda.reject to create a new list passingStudents that contains only the students who received a passing grade (i.e., not a D) from the input list students. The function applies the predicate function (student) => student.grade === 'D' to each element in students. For students with a D grade, the predicate function returns true, and those elements are removed from the resulting list. For students with grades other than D, the predicate function returns false, and those elements are included in the resulting list. Overall, ramda.reject is a useful utility function for creating a new list with elements removed based on a specified predicate function.
