Does Array.prototype.some() return a literal? If so, what does this code mean?

The Array.prototype.some() method returns a boolean value. This is a primitive value, not a "literal".

You are correct that if p holds a boolean value then assigning properties like will not work.

(However, I believe it will only result in an exception if the code is running in strict mode otherwise the attempted assignment will fail silently.)

Even if assigning those .name and .price properties worked that code still doesn't quite make sense because p is a local variable that is not referenced again within that function. It would only make sense if .some() returned a reference to the matching array element, because then it would be an object and the code would update the properties of that object.

JavaScript: Object.prototype.toString(new Number(5)) seems to return a wrong type
toString doesn't take an argument -- it's a method on the object. So if you call Number(5)) (thus passing the Number instance as this) you'll get the expected result: [object Number]. You get similarly bogus results when calling SomeClass.prototype.toString with an argument, for example Number.prototype.toString(new Number(5)) will give '0'. I tested all of t

Creating composite literal of array of arrays
The problem is that [...]elementType is not a valid type name. You can use the syntax with the initialiser syntax like [...]int{1, 2, 3, 4} because the compiler can see how many elements there are to determine the actual type ([4]int in this case). If you want an array-like type that doesn't have a fixed compile time size, use a slice: type t struct { f [][]string } Alternatively, if t

Push an array into another array with Ruby, and return square brackets
What you're seeing is the result of each, which returns the thing being iterated over, or in this case, broken_words. What you want is collect which returns the transformed values. Notice in your original, y is never used, it's just thrown out after being composed. Here's a fixed up version: class Lexicon def initialize(stuff) @words = stuff.split end def self.scan(word) broken_wo

Json Array return null
You're attempting to assign some value to each element of an object. The problem is, you attempt to treat that object like an array, thinking that JS will magically understand what you want to do. It won't. One possible way to actually do what you want: for (var i in abc) if (abc.hasOwnProperty(i)) { abc[i] = "1"; } This way a, b, c properties of abc object will get "1" value. As it st
