Function: applyChangesToString

▸ applyChangesToString(text, changes): string

Applies a list of changes to a string's original value.

This is useful when working with ASTs.

For Example, to rename a property in a method's options:

const code = `bootstrap({
  target: document.querySelector('#app')
})`;

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,
  },
]);

bootstrap({
  element: document.querySelector('#app'),
});
