I need a JavaScript method to allows me to convert the first letter of every word in a string to a capital letter like this: mike tyson wayne to Mike Tyson Wayne.
The method should also be able to convert the first word after an hyphen to capital letter like this: mike-tyson wayne to Mike Tyson Wayne.
The method should also be able to convert uppercase words to capitalize words like this: MIKE-TYSON WAYNE to Mike Tyson Wayne.
I have tried this method using regular expression gotten from another thread:
text.replace(/(^\w{1})|(\s{1}\w{1})/g, match => match.toUpperCase())
It worked for converting the first letter of a string to capital letter and also works for the first letter of a string after space.
I added this expression that was supposed to cater for first letter of a string after space to the expression. The expression is (?:- |\d\. ).*
Combined with the first expression, it became:
text.replace(/(^\w{1})|(\s{1}\w{1})|(?:- |\d\. ).*/g, match => match.toUpperCase());
The problem is that the method above doesn't work for the strings after the dash but still works for the strings after space.
\d is a digit, so your expression matches a - or a digit followed by . ...{1} means one occurrence, which is the default anyways...Try something like this:
/(^\w)|([-\s]\w)/g
A regex like ... /(?<=\b)\w/g or /(?<=\b)\p{L}/gu ... which both use a positive lookbehind for word boundaries but the second variant making use of Unicode property escapes might be a more generic yet viable approach ...
console.log(
"mike-tyson wayne"
.replace((/(?<=\b)\w/g), match => match.toUpperCase())
);
console.log(
"MIKE-TYSON WAYNE"
.toLowerCase()
.replace((/(?<=\b)\p{L}/gu), match => match.toUpperCase())
);.as-console-wrapper { min-height: 100%!important; top: 0; }
