function replaceAll(str, find, replace) {
     return str.replace(new RegExp(find, 'g'), replace);
}
var data = ':['
data = replaceAll(data, ':\[', "/\\");

Error returned: Invalid regular expression: /:[/: Unterminated character class

I have seen other posts relating to this to escape the '[', but I have done that and it doesn't work.

Obviously I'm doing something wrong here and I'm not that familiar with RegEx things, so anybody help please?

You would need to double escape as \ is an escape in a Javascript literal too:

data = replaceAll(data, ':\\[', "/\\");

Change your input like below,

data = replaceAll(data, ':\\[', "/\\");

You need to escape the backslash one more time when putting it inside RegExp constructor.
