Javascript ဟာ <a class="mw-redirect" href="https://en.wikipedia.org/wiki/Prototype-based_programming" title="Prototype-based">prototype-based</a>, multi-paradigm scripting language ဖြစ်ပါတယ်၊ ဆိုလိုတာက dynamic ဖြစ်သလို object-oriented, imperative, and functional programming ရေးသားနည်းပုံစံနဲ့လည်း ထောက်ပံပေးပါတယ်။ အသေးစိတ်ကိုတော့ <a href="/en-US/docs/Web/JavaScript/About_JavaScript">JavaScript</a> အကြောင်း ပိုမို ဖတ်ရှုကြည့်ပါ။</p>
<p>JavaScript စံသတ်မှတ်ချက်ကို <a href="/en-US/docs/JavaScript/Language_Resources">ECMAScript</a> လို့ခေါ်ပါတယ်။ ၂၀၁၂ မှာ modern browsers တွေအကုန်လုံးက ECMAScript 5.1 ကို အပြည့်အဝ support ပေးနေပါပြီ။ Browsers အဟောင်းတွေက အနည်းဆုံး ECMAScript 3 ကို support ပေးပါတယ်။ ဇွန်လ ၁၇ ရက် ၂၀၁၅ မှာ ခြောက်ကြိမ်မြောက် ECMAScript ကို ကြေငြာပြဌာန်းလိုက်ပါတယ်။ အဲ့ဒီ့ version ကို ECMAScript 2015 လို့တရားဝင်ခေါ်ပါတယ်၊ ဒါပေမယ့်လည်း ECMAScript 6 ဒါမှမဟုတ် ES6 ဆိုပြီးလည်းခေါ်ပါတယ်။</p>
<p> ဒီဝက်စာမျက်နှာမှာတော့ JavaScript အကြောင်းကိုပဲ ပြောပြသွားမှာဖြစ်ပါတယ်။Web Pages နဲ့ ဆက်စပ်ပြီးသုံးတဲ့ ဒါမှမဟုတ် တစ်ခြားသော Host Environment နဲ့ စပ်ဆက်ပြီးသုံးတဲ့ အကြောင်းကို ပြောမှ မဟုတ်ပါဘူး။. Web pages နဲ့ စပ်ဆက်ပြီး အသုံးပြုတဲ့ {{Glossary("API","APIs")}} ကို လေ့လာချင်တဲ့ဆိုရင်တော့ <a href="/en-US/docs/Web/API">Web APIs</a> နဲ့ <a href="/en-US/docs/Glossary/DOM">DOM</a> မှာ သွားရောက် လေ့လာလို့ရပါတယ်။</p>
<p>JavaScript ကို <a href="https://en.wikipedia.org/wiki/Java_(programming_language)">Java programming language</a> နဲ့ မတူဘူးဆိုတာ သိထားဖို့လိုပါမယ်။ Java ဆိုတာ U.S. နဲ့ အခြားသောနိုင်ငံတွေမှာ Oracle က မူပိုင်တင်ထားပါတယ်။</p>
