In most time when user want to search something in a text, he/she
wants to do a case insensitive search.
For example to filter items displayed in list on a page.
Also on other applications, say any word processor, or in page search
in Firefox, IE, Chrome etc.
So can we make the default behavior of new methods String.startsWith,
String.contains, String.endsWith case insensitive?
I think all current methods are case-sensitive. If these methods were to
be made case-insensitive, someone else would come on the list demanding
consistency.
Also, it doesn't seem that hard to implement:
String.prototype.startsWithI = function(s){
this.match(new RegExp('^'+s, 'i'));
}
And sometimes, case-sensitive is what you want.
And to make it case sensitive we should add a third flag parameter matchCase
like...
var startsWith = str.startsWith(searchString [, position [, matchCase] ] );
var contained = str.contains(searchString [, position [, matchCase] ] );
var endsWith = str.endsWith(searchString [, position [, matchCase] ] );
Additionally we should have a String.replaceAll method right now web
developers are using complex logic to achieve the same.
"aA".replace(/a/ig, 'b'); // 'bb'
I feel the "i" and "g" flag or regexps aren't that complex. One just
needs to know about them.
