Starts-with test
Learn how to check if a string starts with a specific prefix.
This test checks if a string begins with another string.
A string starts with another string if the latter is a prefix of the former. For example, "Hello world" starts with "Hello".
The test is case-sensitive, meaning that the strings must match exactly, including the case of the letters.
Empty strings are everywhere!
An empty string is a prefix of every string. It follows a math concept called vacuous truth, which says that an empty set is a part of every set.
Syntax
This test has the following syntax:
/*<value>*/ starts with /*<prefix>*/
To negate the test, you can write:
/*<value>*/ does not start with /*<prefix>*/
Parameters
These are the supported parameters:
Examples
Here is a basic example that checks if a string starts with another string:
"Hello world" starts with "Hello" // true

"Hello world" does not start with "Hello" // false
