I am executing the two javascript function 

 

1) function ===>  calling web api and reading the values

 

------if first function return the value  then no need to call the second function

2) second function===> dynamically creating the table 

 

but every time it's calling the second function because first function is working as asynchronous and giving me output after second function execution .

    As I said, nest them

    function functionxyz(){
 // do stuff, do another safe ajax etc etc
}

function functionabc(){

var exists = false;
var variable = some value;
webapi.safeAjax({
 type: "GET",
 url: "api url",
 contentType: "application/json",
 success :function (res){
 res.value.forEach(function(record){
 
 if(record.column==variable ){
 exists=true;
 console.log("Match");
 }else{
 exists=false;
 console.log("Non Match");
 }
 })
 if(exists == true){
 functionxyz();
 }
 }
}

functionabc();

     

    Could also chain webapi.safeAjax(............).then(//next call here etc)

    1) first function
    var exists = false;
    var variable = some value;
    webapi.safeAjax({
        type: "GET",
        url: "api url",
        contentType: "application/json",
        success :function (res){
            res.value.forEach(function(record){
               
                if(record.column==variable ){
                  exists=true;
                  console.log("Match");
                }else{
                  exists=false;
                  console.log("Non Match");
                }
              })
        }
     
    if exists return true then I need to call another function which is calling web api again for different table
    2) function truewebapi ()
     
    if exists return false then I need to call another function which is calling web api again for different table
    3) function falsewebapi ()
     
    again on the basis of  truewebapi() and falsewebapi() function I need to call another function which again calling some web api,But everytime it's giving me false value from first step because of asynchronous call.

    Chain them together or nest them - depending on what you are doing use .then() or call the second one from inside the results of the first one.
