In TypeScript, the function is failing to retrieve the complete array value

I'm facing an issue with a program that is supposed to piece together all the letters, but it's not functioning correctly. I've tried using the debugger, but it doesn't display any errors. Here's the code snippet:

var phrase = [ 'h', 'e', 'l', 'l', 'o',' ', 'w', 'o', 'r', 'l', 'd' ];

let sentence: string[] = createSentence(phrase);

sentence.forEach(letter => {
    console.log(letter);
});

function createSentence(letters: string[]): string[]
{
    var add = "";
    var result: string[] = [];

    phrase.forEach(unionL => {
        if (unionL != ' ') {
            add += unionL;
        } else {
            result.push(add);
            add = "";
        }
    });

    return result;
}

Answer №1

The reason why the entire array is not being pulled is due to the condition specified in the array. To include the last chunk in the result array, you must add another condition. Below is the modified code:

function createSentence(letters: string[]): string[]

{
    var add = "";
    var result: string[] = [];

    phrase.forEach((unionL,index) => {
        if (unionL != ' ') {
            add += unionL;
        } else {
            result.push(add);
            add = "";
        }
        //New Condition
        if(index===phrase.length-1){
            result.push(add);

        }
    });

    return result;
}

Alternatively, you can maintain your existing code and simply append an empty string at the end of the string to align with your logic. For example:

var phrase = [ 'h', 'e', 'l', 'l', ' ', 'w', 'o', 'r', 'l', 'd', ' ' ];
