Visual Presentation:

JavaScript: Split a string and convert it into an array of words

Sample Solution:

JavaScript Code:

// Define a function named string_to_array that takes a string as input
string_to_array = function (str) {
    // Trim the whitespace from the beginning and end of the string, then split the string into an array using whitespace as the separator
    return str.trim().split(" ");
};
// Call the string_to_array function with the input "Robin Singh" and print the result
console.log(string_to_array("Robin Singh"));

Output:

["Robin","Singh"]

Explanation:

In the exercise above,

The code defines a function called "string_to_array()" that takes a string as input. Inside the function:

  • trim() is used to remove any leading or trailing whitespace from the input string.
  • split(" ") is used to split the trimmed string into an array of substrings, with each substring separated by whitespace.
