Splitting strings by both "\\" and "." with regex

Question

I have the following string:

  var str = 'd:\\projects\\my_project\\dist\\js\\example.js'

I want to split the string into an array as follows:

['d:', 'projects', 'my_project', 'dist', 'js', 'example', 'js']

How can do this with str.split(regex)? What is the proper regex I need?

Already tried str.split('(\.|\\)') and str.split('\.|\\') (i.e. w/out parenthesis)

Both '\.' and '\\' work when individually passed, but not combined.

Please help me regex masters!

You are passing string to to split() you need to pass RegExp().

Note: If you will use brackets like /(\.|\\)/) the result will also include . and \\

var str = 'd:\\projects\\my_project\\dist\\js\\example.js'
console.log(str.split(/\.|\\/))

Pass a regular expression to split:

var str = 'd:\\projects\\my_project\\dist\\js\\example.js';
const res = str.split(/\.|\\/);
console.log(res);

.as-console-wrapper { max-height: 100% !important; top: auto; }

You were passing a string - it was looking for a literal pattern .|\ which it couldn't find. A regular expression (regex) uses slashes /, not quotes ' or ".

Other answers already explain that you need to pass a regular expression to String.split() instead of a string. So, alternatively, you can use this regular expression: /[\\.]/. This regular expression defines a Character Set:

var str = 'd:\\projects\\my_project\\dist\\js\\example.js';
console.log(str.split(/[\\.]/));

.as-console {background-color:black !important; color:lime;}
.as-console-wrapper {max-height:100% !important; top:0;}

Thank you all for the help! Tried to upvote you all. – mepley May 11 '19 at 03:15 — mepley, May 11 '19 at 03:15
