I’m trying to replace all spaces within a string with hyphens. I tried this:
h3Text.replace(/\s/, '-');
But it only replaces the first instance of a space and not the ones after it. What is the regex to make it replace all empty spaces?

The replaceAll() method returns a new string with all matches of a pattern replaced by a replacement . The pattern can be a string or a RegExp , and the replacement can be a string or a function to be called for each match.
To replace all occurrences of a substring in a string by a new one, you can use the replace() or replaceAll() method: replace() : turn the substring into a regular expression and use the g flag.
RegEx makes replace ing strings in JavaScript more effective, powerful, and fun. You're not only restricted to exact characters but patterns and multiple replacements at once.
The REGEXREPLACE( ) function uses a regular expression to find matching patterns in data, and replaces any matching values with a new string. standardizes spacing in character data by replacing one or more spaces between text characters with a single space.
try
h3Text.replace(/\s/g, '-');
the g flag is key here. it means global replace, ie replace all
