How to increase each number in a string?
In JavaScript how could I replace every number in a string with that number + 20?
So, this string: "min: 300px and max: 600px, min: 800px"
Would end up as "min: 320px and max: 620px, min: 820px"

To replace all numbers in a string, call the replace() method, passing it a regular expression that globally matches all numbers as the first parameter and the replacement string as the second. The replace method will return a new string with all matches replaced by the provided replacement. Copied!
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. replaceAll() method is more straight forward.
To replace all occurrences of a string in TypeScript, use the replace() method, passing it a regular expression with the g (global search) flag. For example, str. replace(/old/g, 'new') returns a new string where all occurrences of old are replaced with new .
Maybe the shortest version:
"min: 300px and max: 600px, min: 800px".replace(/\d+/g, function(c) {
return parseInt(c, 10) + 20;
});
