How do I compare strings in ReactNative?

Question

im very new to reactNative development. and trying to compare two strings.

ex: response["Result"] equalsTo "True"

i tried using == , toEqual but didnt work.

Updated

im getting JSON Response like this

{ Result: true,
  Message: 'Login Success.',
  Code: 'Login Code' }

when i console.log(response["Result"]) it prints true.

but when i compare. it always go to the else part.

if(response["Result"] == "true"){
    console.log("SUCCESS");
}else{
    console.log("ERROR");
}

react native is actually js,` ==` should be fine. Post more details how "didn't work" — xhg

The problem here is that true is not the same as "true". — Pedro Castilho

Your problem is that the value of Response["Result"] is true, not "true". true is a boolean constant, "true" is a string.

Change your code to:

if(response["Result"]){
    console.log("SUCCESS");
}else{
    console.log("ERROR");
}

and it should work.
