    Array.prototype.some polyfill for 140byt.es

Execute an expression for every element in an array and determine whether one of the elements make the expression evaluate truthy. This polyfill adds the some method to the array prototype for environments lower than ECMAScript 5.

  
## annotated.js
Array.prototype.some = [].some || // Use the native every method if available, otherwise:
  function (
    a, // expression to test each element of the array against
    b, // optionally change the 'this' context for the given callback
    c, // placeholder iterator variable
    d // placeholder variable (stores context of original array)
    ) {
      for (c = 0, d = this; c < d.length; c++) // iterate over all of the array elements
        if (a.call(b, d[c], c, d)) // call the given expression, passing in context, value, index, and original array
          return !0; // if any expression evaluates true, immediately return since 'some' is true
      return !1 // otherwise return false since all callbacks evaluated to false
}

## index.js
Array.prototype.some=[].some||function(a,b,c,d){for(c=0,d=this;c<d.length;c++)if(a.call(b,d[c],c,d))return!0;return!1}
