console.log(owner * 64 + group * 8 + other); // 754 octal permissions
TypeScript
const owner = 7, group = 5, other = 4;
const mode: number = owner * 64 + group * 8 + other;
console.log(mode); // 492 decimal = 0754 octal
Python
print(oct(0o700 | 0o050 | 0o004))  # 0o754
Java
int mode = (7 << 6) | (5 << 3) | 4;
System.out.printf("%o%n", mode); // 754
C#
int mode = (7 << 6) | (5 << 3) | 4;
Console.WriteLine(Convert.ToString(mode, 8)); // 754
