Split string into array [duplicate]

Answer 1

You can try this way:

let entry = prompt("Enter your name") 
let entryArray = entry.split('')
console.log(entryArray)

Answer 2

ES6 :

const array = [...entry]; // entry="i am" => array=["i"," ","a","m"]

Answer 3

Use the .split() method. When specifying an empty string as the separator, the split() method will return an array with one element per character.

entry = prompt("Enter your name")
entryArray = entry.split("");

Answer 4

...and also for those who like literature in CS.

array = Array.from(entry);

Answer 5

ES6 is quite powerful in iterating through objects (strings, Array, Map, Set). Let's use a Spread Operator to solve this.

entry = prompt("Enter your name");
var count = [...entry];
console.log(count);

Answer 6

Do you care for non-English names? If so, all of the presented solutions (.split(''), [...str], Array.from(str), etc.) may give bad results, depending on language:

"प्रणव मुखर्जी".split("") // the current president of India, Pranab Mukherjee
// returns ["प", "्", "र", "ण", "व", " ", "म", "ु", "ख", "र", "्", "ज", "ी"]
// but should return ["प्", "र", "ण", "व", " ", "मु", "ख", "र्", "जी"]

Consider using the grapheme-splitter library for a clean standards-based split: https://github.com/orling/grapheme-splitter
