I'm trying to split my string but not get proper output as per my expected.

Input

let name = "helloguys";

Output

h
he
hel
hell
hello
hellog
hellogu
helloguy
helloguys

let name = "mynameisprogrammer";
for (let index = 1; index <= name.length; index  ) {
  let finalData = name.split(name[index]);
  console.log(finalData[0]);
}

enter image description here

You can use substring to take parts of your input:

let name = "mynameisprogrammer";
for (let index = 1; index <= name.length; index  ) {
  let finalData = name.substring(0, index);
  console.log(finalData);
}

CodePudding user response：

You could use Array.map() along with String.slice() to split the string into the required values:

let name = "mynameisprogrammer";
let result = [...name].map((chr, idx) => name.slice(0, idx   1));

console.log('Result:', result)

.as-console-wrapper { max-height: 100% !important; }

CodePudding user response：

You can simply use a variable and keeping add value of current index and keep printing on each iteration, you don't need split here

let name = "helloguys";

function printName(name) {
  let temp = ''
  for (let index = 0; index < name.length; index  ) {
    temp  = name[index]
    console.log(temp);
  }
}

printName(name)

This is how you could do it. I'm not sure if you wanted them to be object otherwise you could use string.substring

let name = "mynameisprogrammer";
for (let index = 0; index < name.length; index  ) {
  let finalData = name.split("");
  console.log(finalData.slice(0,index 1).join(""));
}

If you need this to be unicode aware, you might want to avoid using string substring / slice etc.

Instead convert to array, and split there.

eg..

let name = "my
