    You can achieve this simply with filter method.

            const day = 'monday';
        const workSchedule = [
        {
            name: 'a',
            age: 21,
            workDays: {
                monday: {isavailable:true}, tuesday:{isavailable:false}, wednesday:{isavailable:true}, thursday:{isavailable:true}, Friday:{isavailable:false}
            }
        },
        {
            name: 'b',
            age: 22,
            workDays: {
                monday: {isavailable:false}, tuesday:{isavailable:false}, wednesday:{isavailable:true}, thursday:{isavailable:false}, Friday:{isavailable:false}
            }
        }
    ];

    
const available = workSchedule.filter(sch=> sch.workDays[day.toLowerCase()].isavailable === true);


console.log(available[0]);
console.log(available[0].name);

    Try like this,

      const workSchedule = [
    {
      name: "a",
      age: 21,
      workDays: {
        monday: { isavailable: true },
        tuesday: { isavailable: false },
        wednesday: { isavailable: true },
        thursday: { isavailable: true },
        friday: { isavailable: false },
      },
    },
    {
      name: "b",
      age: 22,
      workDays: {
        monday: { isavailable: false },
        tuesday: { isavailable: false },
        wednesday: { isavailable: true },
        thursday: { isavailable: false },
        friday: { isavailable: false },
      },
    },
  ];

  const day = "Monday";

  workSchedule.forEach((e) => {
    if (e.workDays[day.toLocaleLowerCase()]["isavailable"]) {
      console.log(e.name + " is available");
    } else {
      console.log(e.name + " is not available");
    }
  });
