To convert binary string to sting you can use parseInt and String.fromCharCode

parseInt converts strings to number. First argument is string value and the second argument is the base value in which the string representation is.

let num = parseInt(binaryStr, 2);

String.fromCharCode converts character code to matching string.

let str = String.fromCharCode(65);

Complete code with example:

const text =  'Hello'    
let binaryStr = text.split('').map(l => l.charCodeAt(0).toString(2)).join(' ');
console.log('Binary string:', binaryStr);

//To convert binary to string
let strVal = binaryStr.split(' ').map(l => String.fromCharCode(parseInt(l, 2))).join('');
console.log('String:', strVal);

Output of above code:

Binary string: 1001000 1100101 1101100 1101100 1101111

String: Hello

let txt="Hello".split('').map(l => l.charCodeAt(0).toString(2)).join(' ')
       
let s = txt.split(" ").map(w=> String.fromCharCode(parseInt(w,2)))

console.log(s.join(""))

Just convert binary string back to integer and map those values to character using fromCharCode
