export default class ParserState {
State tracking for an in-progress parse and render.
export default class ParserState {
constructor(progress) {
Tracks the number of capture groups in the expression.
this.groupCounter = 1;
Cancels the in-progress render when set to true.
this.cancelRender = false;
Warnings that have been generated while rendering.

Used to display the progress indicator
this._renderCounter = 0;

}
Counts the number of in-progress rendering steps. As the counter goes up, a maximum value is also tracked. The maximum value and current render counter are used to calculate the completion process.
