What am I doing wrong in this code?

Question

1.00/5 (1 vote)

See more:

Write a function called stringIncludes, which accepts two strings: the first string is a word and the second string is a single character.

The function should return true if the first string includes the character, otherwise it should return false.

Do not use the built in String.includes() function!

stringIncludes('awesome', 'e'); // true
stringIncludes('awesome', 'z'); // false

What I have tried:

function stringIcludes(str1, char) {
if(str1.includes(char) ) {
return true;
}
else {
return false;
}
}
('awesome', 'e')
('awesome', 'z')

You didn't followed requirements!
you are requested to "Do not use the built in String.includes() function!" and your code uses it:

JavaScript

if(str1.includes(char) ) {

you forgot to tell the function name and the semi column at the end of lines:

JavaScript

('awesome', 'e')
('awesome', 'z')

you can simplify the code to:

JavaScript

function stringIcludes(str1, char) {
    return str1.includes(char);
}
}

Thank you

But your code still uses String.includes().

I didn't intend to do the homework in full :)

Richard MacCutchan 7-May-20 7:47am

Quite right too. :)

So, is there a way of writing the code without using string.includes()?

Solution 2

You are supposed to implement the following algorithm:

Enumerate the letters of first parameter.

If current letter equals second parameter, return true.

Return false.
