Sorting to another array-CodePudding

I have a problem when trying to sort an array alphabetically into another array.

This is what the original array looks like:

var palavras = new Array(5);

palavras[0] = "Português";
palavras[1] = "Inglês";
palavras[2] = "Programação C";
palavras[3] = "Programação JS";
palavras[4] = "Educação Física";

I need to sort this array alphabetically into another array but I can't seem to get it to work.

This is the expected output of the other array:

arraySorted[0] = "Educação Física";
arraySorted[1] = "Inglês";
arraySorted[2] = "Português";
arraySorted[3] = "Programação C";
arraySorted[4] = "Programação JS";

I'm new to StackOverflow so I don't know how to use the tools to make it more understandable but I hope someone can help. Thanks!

CodePudding user response：

If I understand correctly, You want to keep original array unsorted. So you have to create new array from original one:

arraySorted = palavras.slice()

and then you can sort:

arraySorted.sort()

Array.slice() returns new array, without any param it returns array with the same values and length. Array.sort() changes array original array so without slice you would have both arrays changed
