Function: composeContext()
composeContext(
params
):string
Composes a context string by replacing placeholders in a template with corresponding values from the state.
This function takes a template string with placeholders in the format {{placeholder}}
and a state object.
It replaces each placeholder with the value from the state object that matches the placeholder's name.
If a matching key is not found in the state object for a given placeholder, the placeholder is replaced with an empty string.
Parameters
• params
The parameters for composing the context.
• params.state: State
The state object containing values to replace the placeholders in the template.
• params.template: string
The template string containing placeholders to be replaced with state values.
Returns
string
The composed context string with placeholders replaced by corresponding state values.
Example
// Given a state object and a template
const state = { userName: "Alice", userAge: 30 };
const template = "Hello, {{userName}}! You are {{userAge}} years old";
// Composing the context will result in:
// "Hello, Alice! You are 30 years old."
const context = composeContext({ state, template });
