I am currently working on a series of JavaScript tests available at js-assessment
One of the tasks states:
it("you should be able to find all occurrences of an item in an array", function() {
var result = answers.findAllOccurrences('abcdefabc'.split(''), 'a');
expect(result.join(' ')).to.be('0 6');
});
I am confused about the '0 6' result provided. The task requires finding occurrences of 'a', but there are only two 'a's in that array.
I am not familiar with the exact implementation of findAllOccurrences, but based on the output, it seems to be carrying out the following steps:
It requires an Array and a String as input. The function then returns an Array containing the indices where the specified String occurs.
'abcdefabc'.split('') //=> ["a", "b", "c", ...]findAllOccurrences
The function findAllOccurrences locates occurrences of "a" at the first (index: 0) and seventh (index: 6) positions within this input Array, resulting in: [0, 6]
[0, 6].join(" ") will produce "0 6"
