The JS Case Converter collection helps changing the cases of existing texts.
Import caseconverter.js into your JS project or HTML page and use the functions of the CaseConverter object:
<!DOCTYPE html>
<html>
<head>
<script src="caseconverter.js"></script>
</head>
<body>
<script>
var input = "The quick brown fox jumps over the lazy dog";
CaseConverter.convertToUpperCase(input); // THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG
CaseConverter.convertToLowerCase(input); // the quick brown fox jumps over the lazy dog
CaseConverter.convertToStartCase(input); // The Quick Brown Fox Jumps Over The Lazy Dog
CaseConverter.convertToCamelCase(input); // TheQuickBrownFoxJumpsOverTheLazyDog
CaseConverter.convertToSnakeCase(input); // The_Quick_Brown_Fox_Jumps_Over_The_Lazy_Dog
CaseConverter.convertToKebabCase(input); // the-quick-brown-fox-jumps-over-the-lazy-dog
CaseConverter.convertToStudlyCaps(input); // thE qUIck BRoWN foX jUMPs oVeR tHe lAZY doG
CaseConverter.invertCase(input); // tHE QUICK BROWN FOX JUMPS OVER THE LAZY DOG
</script>
</body>
</html>If you want to use a minified version of caseconverter.js, you have to minify it before usage. One way is to run the minifier tool via npm.
Installing:
[sudo] npm install [-g] minifier
Minifying:
minify --output caseconverter.min.js caseconverter.js
