javascript - Print method parameter names where last parameter is a spread parameter in ES5 -

how print console signature of method last parameter rest parameter in typescript (es5) ?

for example following method:

public execute(params1: number, params2: number, ...allotherparams:number[]){       // dosomething...     } 

should print out:

execute(params1, params2, ...allotherparams)

i stuck @ rest parameter following solution not show rest parameter:

let funcsignature = this.execute.tostring(); console.log(funcsignature); 

i getting this:

function (params1, params2) {     var allotherparams = [];     (var _i = 2; _i < arguments.length; _i++) {         allotherparams[_i - 2] = arguments[_i];     }     // dosomething... } 

function execute(params1, params2, ...allotherparams) {    //dosomething  }    // third parameter not shown in console.log ?  console.log(execute.tostring());

this possible if typescript compiled es6 (and higher) javascript standard.

for instance following typescript code:

function execute(params1: number, params2: number, ...allotherparams:number[]){     // dosomething... }  

when target set es5 code compiled into:

function execute(params1, params2) {     var allotherparams = [];     (var _i = 2; _i < arguments.length; _i++) {         allotherparams[_i - 2] = arguments[_i];     }     // dosomething... } 

and when target set es6 code compiled into:

function execute(params1, params2, ...allotherparams) {     // dosomething... }
