I am working on a "fill in the blanks" card game, (very) similar to Cards Against Humanity. In some cases, I want to update a string of text with multiple blanks ("My ______ is ______.", for example), but I'm having trouble replacing these identical blank fields with different strings. Let's say I'd like to turn my string into "My cat is white". How could I possibly make this happen? I can replace every blank space in my strings with the same piece of text, but I can't seem to alternate between them. I guess I could cut my string into pieces every time a blank space ends, replacing all fragments with the text I want, and then joining the strings together... but is there a simpler way?

Thanks in advance!

You may try internally using placeholders in your input string. That is, consider using the following representation:

My {1} is {2}.

When you want to display the original version you had to your users, simply replace the {1}, {2}, etc. placeholders with underscores. Then, when you need to fill in a particular blank, target the placeholder directly.

var input = "My {1} is {2}.";
var display = input.replace(/\{\d+\}/g, "______");
var result = input.replace("{1}", "cat");
result = result.replace("{2}", "white");
