Question

Write a JavaScript function that prints all the symbols of a string, each on a new line. The input comes as a single string argument.

Examples:

Input:

'Hello, World!'

Output:

str[0] -> H
str[1] -> e
str[2] -> l
str[3] -> l
str[4] -> o
str[5] -> ,
str[6] -> 
str[7] -> W
str[8] -> o
str[9] -> r
str[10] -> l
str[11] -> d
str[12] -> !

---

The output is printed on the console, each letter on a new line.

Answer 1

Here is the function:

function printStr(strInput) {
    for (let i = 0; i < strInput.length; i++) {
        console.log(`str[${i}] -> ${strInput[i]}`);
    }
}

printStr("Hello, World!");

 

Answer 2

Another solution with for in:

function print(str) {
    for (let i in str) {
        console.log(`str[${i}] -> ${str[i]}`);
    }
}

print("Hello, World!");
