How to add something in existing element of an array?

Question

To be specific: Let consider this array -

var strings = ['John', 'Jane', 'Mary'];

Now the question is how can I add something to that existing element in array like I want to append |Teacher in John so that it would be John|Teacher.

So altogether, I want is -

var strings = ['John|Teacher', 'Jane|Doctor', 'Mary|Housekeeper'];

How can I do this? Please help.

Iterate over the array and append |Teacher to every element. Use a for loop or the Array.map function to iterate over elements. — bamtheboozle

Get the content of the array at index i, modify the string, store the value back at index i — Andreas

The question is unclear. When do you want to add Teacher, Doctor, Housekeeper ? — yuantonito

Try this:

var strings1 = ['John', 'Jane', 'Mary'];
var strings2 = ['Teacher', 'Doctor', 'Housekeeper'];
var strings = strings1.map(function(e, i) {return e + '|' + strings2[i];});

Awesome. Also did it with forEach! Thanks a lot.

Why are you returning an Array from the map callback?

@llama: Returning the array that this dude was asking for.

@llama: Oh well, I just "alerted" the results, so probably missed that. You can simply remove the [ and ] (which I just did myself).
