Output: Array address: 0x7ffe9472bad0 Array = 0x7ffe9472bad0 Array = 0x7ffe9472bad4 Array = 0x7ffe9472bad8 Array = 0x7ffe9472badc Array = 0x7ffe9472bae0 Array = 0x7ffe9472bae4Īs we can see on this example, the first element and the array itself points to the same memory location, so it is 0 elements away from the location of the array itself. To illustrate that, we can run the C program below: #include int main() “Referencing memory by an address and an offset is represented directly in computer hardware on virtually all computer architectures, so this design detail in C makes compilation easier … “ - Wikipedia In this post, we are going to take a closer look at the JavaScript forEach method. Each method has different features, and it is up to you, depending on what you're doing, to decide which one to use. In C an array points to the location in the memory, so in expression array, n should not be treated as an index, but as an offset from the array’s head. JavaScript has powerful semantics for looping through arrays and array-like objects. The JavaScript forEach method is one of the several ways to loop through arrays. The most common answer to the array numbering question, points out that zero-based numbering comes from language design itself.
