Generate rows of TS function types.js

let rows: string[] = [];
for (let count = 1; count <= 10; count++) {
    let numbers = Array.from(new Array(count)).map((x, i) => i + 1);
    let genericDef = numbers.map(x => `T${x} extends string`).join(', ');
    let parameterDef = numbers.map(x => `a${x}: T${x}`).join(', ');
    let recordDef = numbers.map(x => `T${x}`).join('|');
    rows.push(`<${genericDef}>(strings: TemplateStringsArray, ${parameterDef}): HasRouteTemplate & ((r: Record<${recordDef}, string>) => string);`);
}

console.log('\n\n' + rows.join('\n'));
