Question

friends.

I have an array and it contains some string values.
ex: array name=”All_array”

Now i want to check all values in that array for first character of a string.

if a String starts with character ‘a’ then move that string to array called “A_array”.
if a String starts with character ‘b’ then move that string to array called “B_array”.

How to achieve this task.

Answer 1

var splitArrays = {};
for(var i = 0; i < All_array.length; ++i){
    var firstChar = All_array[i].substr(0,1).toUpperCase();
    if(!splitArrays[firstChar + '_array'])
        splitArrays[firstChar + '_array'] = [];
    splitArrays[firstChar + '_array'].push(All_array[i]);
}

This will take every element in All_array and put them into an object containing the arrays indexed by the first letter of the elements in All_array, like this:

splitArrays.A_array = ['Abcd','Anej','Aali']

etc…
