The expression is evaluated from left to right. 
True && 4/3 is evaluated first. This is a logical AND operation, so both operands must be truthy for the expression to be truthy. True is truthy, and 4/3 is truthy because any non-zero number is truthy in JavaScript. So this expression evaluates to truthy. 
Then, truthy || !6 is evaluated. This is a logical OR operation, so at least one operand must be truthy for the expression to be truthy. Since the first operand (True && 4/3) is truthy, the whole expression is truthy. Therefore, the value of the expression is true.
