osm2geojson-ultra/dist/late-binder.js

a faster & more complete OSM & Overpass (either in xml or in json formats) to geojson convertor - 4x faster than xmldom + osmtogeojson in most situations - implemented in TypeScript with txml for XML parsing

export class LateBinder {
    constructor(container, valueFunc, ctx, args) {
        this.container = container;
        this.valueFunc = valueFunc;
        this.ctx = ctx;
        this.args = args;
    }
    bind() {
        const v = this.valueFunc.apply(this.ctx, this.args);
        const idx = this.container.indexOf(this);
        if (idx < 0) {
            return;
        }
        const args = [idx, 1];
        if (v) {
            args.push(v);
        }
        this.container.splice(...args);
    }
