Javascript - umumiy maqsadga yo'naltirilgan scripting til bo'lib, 

ECMAScript tomonidan belgilangan spetsifikatsiyalarga javob beradi. 

Boshqacha qilib aytganda, ECMAScript scripting til uchun reja (blueprint, 

standard) bo'lsa, Javascript esa bu standard'ning amalga oshirilishidir.

Javascript Netspace'ning Java appletlarini qo'llab quvvatlashidan kelib

foydalanib, e'tibor tortishga urinishgan deb aytiladi.
