A tweet-sized, fork-to-play, custom split function implementation, lol. But it is very very slow!
var path = '/home/charlike/dev/kdf/templates/index.js';
var _split = function(a,b){var c=[],d='',i=0,j=0,f;while(i<a.length){f=a[i++];if(f===b){j++;d=''}else{d=d+f;c[j]=d}}if(!c[0]){c[0]=''}return c}
_split(path, '/');
//=> ['', 'home', 'charlike', 'dev', 'kdf', 'templates', 'index.js']| function( | |
| a, /* incoming string that will split */ | |
| b /* based on some character */ | |
| ) { | |
| var c = [], // array that we will return finally | |
| d = '', // used for caching | |
| i = 0, // character iterator | |
| j = 0, // array key | |
| f; // current character | |
| while (i < a.length) { // loop over all chars in string | |
| f = a[i++]; // get current char | |
| if (f === b) { // check if it is equal to the given `b` | |
| j++; // we should increase array key | |
| d = '' // and we should reset string cache | |
| } else { // otherwise | |
| d = d + f; // we concatenate current char with previous char | |
| c[j] = d // and write current state to as array value | |
| } | |
| } | |
| if (!c[0]) { // weird, but we should check if first value | |
| c[0] = '' // of the constructed array is undefined | |
| } // if it is, reset it to null string | |
| return c // return array that we built | |
| } |
| function(a,b){var c=[],d='',i=0,j=0,f;while(i<a.length){f=a[i++];if(f===b){j++;d=''}else{d=d+f;c[j]=d}}if(!c[0]){c[0]=''}return c} |
