Element-wise Operations

This feature allows you to perform element-wise operations on arrays. In the example, the `add` function adds a scalar value to each element of the input array `b` and stores the result in array `a`.

const cwise = require('cwise-compiler');

const add = cwise({
  args: ['array', 'array', 'scalar'],
  body: function(a, b, c) {
    a = b + c;
  }
});

const a = [1, 2, 3];
const b = [4, 5, 6];
add(a, b, 10);
console.log(a); // Output: [14, 15, 16]

Custom Reduction Operations

This feature allows you to define custom reduction operations. In the example, the `sum` function calculates the sum of all elements in the input array `a`.

const cwise = require('cwise-compiler');

const sum = cwise({
  args: ['array'],
  pre: function() {
    this.sum = 0;
  },
  body: function(a) {
    this.sum += a;
  },
  post: function() {
    return this.sum;
  }
});

const a = [1, 2, 3, 4];
const result = sum(a);
console.log(result); // Output: 10

Conditional Operations

This feature allows you to perform conditional operations on arrays. In the example, the `threshold` function sets elements of the input array `a` to 0 if they are less than the scalar threshold value `t`.

const cwise = require('cwise-compiler');

const threshold = cwise({
  args: ['array', 'scalar'],
  body: function(a, t) {
    if (a < t) {
      a = 0;
    }
  }
});

const a = [1, 5, 3, 7];
threshold(a, 4);
console.log(a); // Output: [0, 5, 0, 7]
