like below fixes the issue I want to write a function which returns me formatted string. I wrote a random function "pickRandom" do I get always one random string from the array. , You could use arguments spread syntax
code :
const randomOutput = (arrayToChange, ...variables) => {
  const randomString = pickRandom(arrayToChange);

  return util.format(randomString, ...variables);
}

should help you out I want to create simple function that split string by camelCase. The problem when i write the code as a function and try to use this, it doesnt working. , Try this instead - you aren't returning a result in your method.
code :
function cutCamelCase(str) {
  return str.split(/(?=[A-Z])/).map(function(s) {
    return s.toLowerCase();
  });
}

With these it helps Having clean and easy to use classes is not only necessary for the public API.
Having internal code hard to read and use is not acceptable.

hope this fix your issue I have function, that makes animation on DOM elements using animate.css when user scrolling the page on certain coordinates. It works perfectly. , I think your answer is here:
JavaScript Nested Functions
code :
function elemAnimate(selector,position,name,method){
  $(window).scroll(function() {
    $(selector).each(function() {
      if ($(this).offset().top < $(window).scrollTop() + position) {
        slideAnimate(name,method);
      }
    });
  });
}

function slideAnimate(name,method){
  $(name).addClass(method === undefined || method === 'default' ? 'slideInLeft' : method);
}
function elemAnimate(selector,position,name,method){
  $(window).scroll(function() {
    $(selector).each(function() {
      if ($(this).offset().top < $(window).scrollTop() + position) {
        $(name).addClass(method === undefined || method === 'default' ? 'slideInLeft' : method);
      }
    });
  });
}

What could parametrs of FFT function mean


By : A.Nofal
Date : September 26 2020, 05:00 AM
it helps some times This code is only part of an FFT. a is input. b is output. w contains precomputed weights. l is a number of subdivisions at the current point in the FFT. m is the number of elements per division. The data in a, b, and w is interleaved complex data—each pair of double elements from the array consists of the real part and the imaginary part of one complex number.
The code performs one radix-two butterfly pass over the data. To use it to compute an FFT, it must be called multiple times with specific values for l, m, and the weights in w. Since, for each call, the input is in a and the output is in b, the caller must use at least two buffers and alternate between them for successive calls to the routine.
code :
double a[4] = { 0, 0, 0, 0 };
double b[4] = { 0, 0, 0, 0 };
double w[8] = { 1, 0, 0, 0, 0, 0, 0, 0 };
int m = 3;
int l = 8;
 
fft(a, b, w, m, l);
