Trying to write a javascript function for comparing only first character of 2 strings but can't make it work. Here is the code.
function compare(wordOne, wordTwo) {
if (wordOne.substring(0) === wordTwo.substring(0))
{
return true;
} else {
return false;
}
}
compare("house", "hell");
Assuming you want to compare the first letter of the two strings, you can use the following code
function compare(wordOne, wordTwo) {
return wordOne[0] === wordTwo[0];
}
compare("house", "hell");
This condenses the if
/else
condition, as you are just interested in whether the first letters are equal - not in how different they are.
You can also use str.toUpperCase()
(or) str.toLowerCase()
in order to make the comparison case insensitive.
As per @Josh Katofsky's suggestion, you can of course make this function more versatile by - for instance - adding a third parameter that tests the n-th letter:
function compare(wordOne, wordTwo, index) {
return wordOne[index] === wordTwo[index];
}
compare("house", "hell", 0);
