Javascript array index difference from [ ] to ( )

[talha-rafique]

in javascript and in solidity if you need to get gata from array index you can write like that
let data = array[0]
but in the testing phase, i saw javascript got data from array like this array(0)
as i know, in javascript and solidity, array works like that array [ index ] but how is this working. ?????

@talha-rafique Solidity created getter functions for all public state variables, and in case of array it create a getter function with a index as a parameter, so you can pass the index and get the element from the array. It is same like this:

function getElement(uint256 index) returns (type-of-element) {
   return array[index]
}

@talha-rafique but this all happens internally that's why you do not see any getter in code.
