I am trying to figure out how to make a regex that can match spaces in between braces. So that these exact white spaces could be removed.

SOMETHING({ 1, 2, 3, 4, 5 },{ 2, 4, 6, 8, 10 }, "My text with spaces)

should be come

SOMETHING({1,2,3,4,5},{2,4,6,8,10}, "My text with spaces)

I am not strong in regex and I tried to adapt the following function without luck. It gets the value between curly brackets, but I am not sure what to do to select only the white spaces between these brackets

str.replace(/[^{\}]+(?=})/g,'');

Selected solution

str.replace(/\s+(?=[^{}]*})/g,'');
