I need a function that works like split
var string = "a|b|c"
console.log(string.split('|'))
to get a string and split it using loop
function splitstr(str, charToSplit){
}
I want the output of ('a|b|c', '|') to be ["a", "b", "c"]

Here is a slightly simpler solution that works correctly:
function splitStr(str, separator) {
const parts = [];
let nextPart = '';
for (let i = 0; i <= str.length; i++) {
if (str[i] === separator || i === str.length) {
parts[parts.length] = nextPart;
nextPart = '';
} else {
nextPart += str[i]
}
}
return parts;
}
console.log(splitStr("abc|abcd|ac", "|"));

You can use the code below.
This code had 8 steps to it.
- Loops through the string
- Checks if the current item is equal to
charToSplit - If it is, it loops through the values in between
startIndexand your current index (excluding your current index, which is the character you want to split on) - It first sets the value of
output[currentIndex]to an empty string (since using+=on something that doesn't exist doesn't work correctly - Then it adds the current letter you are on to
output startIndexis set to your current index + 1 (which is the character after the character that you want to split on)currentIndexis increased by 1 since you're now on the next set of values- Finally, the code returns
output
Note: The final extra loop after the first loop is there to add the last value to your output array.
function splitstr(str, charToSplit) {
var output = [];
var currentIndex = 0;
var startIndex = 0;
for (var i = 0; i < str.length; i++) {
if (str[i] == charToSplit) {
output[currentIndex] = "";
for (var x = startIndex; x < i; x++) {
output[currentIndex] += str[x];
}
startIndex = i + 1;
currentIndex++;
}
}
output[currentIndex] = "";
for (var i = startIndex; i < str.length; i++) {
output[currentIndex] += str[i];
}
return output;
}
console.log(splitstr("abc|abcd|ac", "|"));6 Comments

Thanks but are there any other way to do this by not using built-in functions
push and subtring ??Ar3f
Thanks a lot for explaining every step, appreciate that.

@NewUser yw. Give me a few mins to work on a solution without built-in functions

@NewUser I updated my snippet to work without built in functions. Let me update my explanation

Thanks a lot, how about the output of
('abc|abcd|ac', '|') shoudn't it be ["abc","abcd","ac"] ??? cause it returns ["c", "d", "c"] (it returns the last char of the string) |
