Benchmark path-planning algorithm written in TypeScript in the browser

Use the following process:

• Transpile via the TypeScript playground
• Benchmark via benchmark.js

For example, this TypeScript code:

function add(x: number, y: number): number {
    return x + y;
}

console.log(add(2,2)); // 4

Can be benchmarked after transpilation as follows:

var bench1 = new Benchmark(
  {'fn':add, 'cycles':0,'count':1,'name':'bench1','async':true}
);

function add(x, y) {
    return x + y;
}

function log(result){console.log(JSON.parse(JSON.stringify(result.target.stats)))};

bench1.on('complete', log);
bench1.run();

JavaScript is typescript, so start writing your performance test in typescript. The only ting typescript could affect performance that I can think of is which target do you use in tsconfig.json - probably es5 will be slower than es2018 because of pollyfills. Also language features that don't exists in js standard would be interesting to test, for example https://www.typescriptlang.org/docs/handbook/decorators.html
