jsPerf.app is an online JavaScript performance benchmark test runner & jsperf.com mirror. It is a complete rewrite in homage to the once excellent jsperf.com now with hopefully a more modern & maintainable codebase.
jsperf.com URLs are mirrored at the same path, e.g:
https://jsperf.com/negative-modulo/2
Can be accessed at:
https://jsperf.app/negative-modulo/2
var mystring = 'okay.this.is.a.string';
var re = new RegExp(".","gm");
window.replaceAll = function( _str, token, newToken, ignoreCase ) {
var _token;
var str = _str;
var i = -1;
if ( typeof token === "string" ) {
if ( ignoreCase ) {
_token = token.toLowerCase();
while( (
i = str.toLowerCase().indexOf(
token, i >= 0 ? i + newToken.length : 0
) ) !== -1
) {
str = str.substring( 0, i ) +
newToken +
str.substring( i + token.length );
}
} else {
return _str.split( token ).join( newToken );
}
}
return str;
}
Ready to run.
