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.

|---|---|---|
params | Object | 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

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 });
