Geeeting particular value from json and store in one variable

I need to get a particular value from the JSON and store it in the variable in LWC is there any way I can do it:

asd==[
   {
      "ABC":"ytyffy98948",
      "custui":"009686758jbnvnvm",
      "CAR__c":"YUI",
      "RAF__C":f,
      "FAN__C":"78tu8u"
      
      
   }
]
const sdfr== asd.FAN__C;

I am getting the value in sdfr as undefined. the actual value in JSON is 78tu8u

kindly help me out for this.

asd=[
   {
      "ABC":"ytyffy98948",
      "custui":"009686758jbnvnvm",
      "CAR__c":"YUI",
      "RAF__C":"f",
      "FAN__C":"78tu8u"  
   }
]

const sdfr = asd[0].FAN__C;
