I'm attempting the following:  var a1 = ['a', 'e', 'f'];  // [a, e, f] var a2 = ['b', 'c', 'd'];  // [b, c, d] a1.splice(1, 0, a2);       // expected [a, b, c, d, e, f]                            //...

I just want to confirm if the following two Javascript statements produces the same results, as it seems to me:  First:  var element = my_array.splice(0,1)[0];   Second:  var element = my_array.shift();   I want to substitute the first by the second,...

I've been trying to implement a function where given with two arrays,  array1's elements is used as conditions to filter out elements in array2.  For instance:  array1= [apple, grapes, oranges]  array2= [potato, pears, grapes, berries, apples...

In the CoffeeScript docs for array splicing, what is the purpose of the trailing , _ref?  CoffeeScript:  numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] numbers[3..6] = [-3, -4, -5, -6]   Compiles to:  var numbers, _ref; numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8...

var newlist = list.slice( 0, pos ).concat( tasks ).concat( list.slice( pos ) );   This makes me shudder just looking at it....

Suppose I have an array like this:  myArray = ["a","b","c","d","e"]   And I want to loop through it to find specific values and remove them.  for(var i=0;i<myArray.length;i++){     if(myArray[i] == "b...

I am using CoffeeScript along with the JS splice function.  My understanding of the JS splice function is that it should return the objects that were spliced out and modify the original array.  This seems to work ok with simple arrays but when I star...

I have an array arr:  arr = [0,1,2,3,4,5]  How can I reorder/ shift multiple elements? For example,   I want to remove 0,2 and 3 and put them at index 4 so that the final array should be [1,0,2,3,4,5]   In the above example, index 4 is with the persp...
