Quick start

A usage example from the jsonc-parser README.

typescriptFull README ↗
/**
 * Creates a JSON scanner on the given text.
 * If ignoreTrivia is set, whitespaces or comments are ignored.
 */
export function createScanner(text: string, ignoreTrivia: boolean = false): JSONScanner;

/**
 * The scanner object, representing a JSON scanner at a position in the input string.
 */
export interface JSONScanner {
    /**
     * Sets the scan position to a new offset. A call to 'scan' is needed to get the first token.
     */
    setPosition(pos: number): any;
