Regex to replace anything not precceded a word

Question

I want to replace string containing b- with bst-. The edge cases are b- should not be preceded by any letter.

input = "b-picker-wrap b-active bob-state-default .b-picker /b-pic";

output = "bst-picker-wrap bst-active bob-state-default .bst-picker /bst-pic";

str.replace('b-', 'bst-'); – Álvaro Touzón Aug 29 '17 at 06:37 — Álvaro Touzón, Aug 29 '17 at 06:37

Use the following approach:

var input = "b-picker-wrap b-active bob-state-default .b-picker /b-pic",
    result = input.replace(/\bb-/g, "bst-");
    
console.log(result);
