Basic East Functions - Examples
This file contains simple examples to get started with East functions.
Example 1: Increment Function
Adds 1 to an integer:
return East.function([East.IntegerType], East.IntegerType, ($, x) => {
return $.return(x.add(1n));
});
Example 2: Add Two Integers
Adds two integers together:
return East.function(
[East.IntegerType, East.IntegerType],
East.IntegerType,
($, x, y) => {
return $.return(x.add(y));
}
);
Example 3: String Concatenation
Appends "!" to a string:
return East.function([East.StringType], East.StringType, ($, s) => {
return $.return(s.concat("!"));
});
Example 4: Boolean Comparison
Checks if an integer is greater than zero:
return East.function([East.IntegerType], East.BooleanType, ($, x) => {
return $.return(East.greater(x, East.value(0n)));
});
Example 5: Float Multiplication
Doubles a float value:
return East.function([East.FloatType], East.FloatType, ($, x) => {
return $.return(x.multiply(2.0));
});
Testing These Examples
Each example can be validated using the east_compile tool:
{
"typescript_code": "<paste example code here>"
}
If compilation succeeds, you'll receive the serialized IR. If it fails, you'll get a clear error message explaining what needs to be fixed.
