So I have a list of variables in the file which I want to convert into all capitals separating underscores in javascript.
variable pattern is like this:
AwsKey
AwsSecret
CognitoUserPool
which I want to convert like below:
AWS_KEY
AWS_SECRET
COGNITO_USER_POOL
how do I write a function which does this in javascript? Any help would be much appreciated. Thank you.
Edit: Sorry I forgotten to make them upper case
function camelToCaps(str) { return str.replaceAll(/([A-Z])/g, '_$1').replace(/([a-z])/, '$1).toUpperCase().slice(1); } const camels = [ 'AwsKey', 'AwsSecret', 'CognitoUserPool', ]; function camelToCaps(str) { return str.replaceAll(/([A-Z])/g, '_$1').toUpperCase().slice(1); } const caps = camels.map(camelToCaps); console.log(caps);
