|
|
})`;
|
|
|
|
const indexOfPropertyName = 13; // Usually determined by analyzing an AST.
|
|
const updatedCode = applyChangesToString(code, [
|
|
{
|
|
type: ChangeType.Insert,
|
|
index: indexOfPropertyName,
|
|
text: 'element',
|
|
},
|
|
{
|
|
type: ChangeType.Delete,
|
|
start: indexOfPropertyName,
|
|
length: 6,
|
|
},
|
|
]);
