Script Preparation code:

var strTxt = Array(100).fill("@".repeat(128)).join(" "), len = 4, asize = Math.ceil(strTxt.length/len);

Tests:

RegEx Match
var ar = strTxt.match(new RegExp('.{1,'+len+'}','g'));
For Slice
var ar = Array(asize); for(i=0,y=0;i<asize;i++,y=i*len){ ar[i] = strTxt.slice(y,y+len); }
For SubStr
var ar = Array(asize); for(i=0,y=0;i<asize;i++,y=i*len){ ar[i] = strTxt.substr(y,len); }
While Slice
var ar = Array(asize),i = 0; while(i<asize){ ar[i] = strTxt.slice(i*len,i*len+len); i++; }
While SubStr
var ar = Array(asize),i = 0; while(i<asize){ ar[i] = strTxt.substr(i*len,len); i++; }
Generator SubStr
var ar = [...(function *(){for(i=0;i<asize;i++){yield strTxt.substr(i*len,len);}})()];
Map SubStr
var ar = [...Array(asize)].map((v,i)=> strTxt.substr(i*len,len));
