Benchmark: jsspltttttttt - MeasureThat.net

Script Preparation code:

var strTxt = Array(100).fill("@".repeat(128)).join(" "), len = 128;

Tests:

testttttt
var ar = strTxt.match(new RegExp('.{1,'+len+'}','g'));
tesstttt2
var ar = Array(Math.ceil(strTxt.length/len)), arlen=ar.length; for(i=0,y=0;i<arlen;i++,y=i*len){ ar[i] = strTxt.slice(y,y+len); }
tesstttt3
var ar = Array(Math.ceil(strTxt.length/len)), arlen=ar.length; for(i=0,y=0;i<arlen;i++,y=i*len){ ar[i] = strTxt.substr(y,len); }
tesstttt4
var ar = Array(Math.ceil(strTxt.length/len)), arlen=ar.length,i = 0; while(i<arlen){ ar[i] = strTxt.slice(i*len,i*len+len); i++; }
tesstttt5
var ar = Array(Math.ceil(strTxt.length/len)), arlen=ar.length,i = 0; while(i<arlen){ ar[i] = strTxt.substr(i*len,len); i++; }
