I was wondering how the syntax of the b.startsWith() function in basil.js is supposed to look.

I want to check all words of a text to see, if they start with the string 'some' (like 'sometimes', 'something', 'someone', 'somewhere' etc.).

So, I create a variable that passes on every word of my text to the b.startsWith() function.

When I put the string I am searching for in the brackets ( b.startsWith(some) ), then where exactly will I have to put the variable that will be checked if it starts with my 'some'-string?

  • Make your own. `indexOf` isn’t a good way to go about that check, and `String#startsWith` is coming in ES6. =) `if (!''.startsWith) { String.prototype.startsWith = function(prefix) { return this.substring(0, prefix.length) === prefix; }; }` – Ry- Mar 10 '14 at 05:25

It looks like their documentation has some errors. It shows the function signature as you have described:

b.startsWith(str)

But if you look at the code where the function is defined it looks like this:

var startsWith = pub.startsWith = function(str, prefix) {
  return str.indexOf(prefix) === 0;
};

The first argument is the string to search through, and the second argument is the string to search for.

There was indeed an error in our documentation. It's fixed now, thanks for letting us know.

So you can use it as

var trueOrFalse = b.startsWith( yourWord, yourSearchToken );
