More than half of all deaths involved people 60 years and older, of whom 22 million were people aged 70 years and older, and 10.7 million were people aged 80 years and older. Almost one in five deaths in the world was of a child under the age of five years (Figure 1) .IV/AIDS and TB are the sixth and seventh most common causes of death respectively, and together caused 3.5 million deaths in 2004.As may be expected from the very different dis-tributions of deaths by age and sex, there are major differences in the ranking of causes between high-and low-income countries (Table 2) .
Javascript is Ecmascript. EcmaScript is a standardised version of JavaScript. JavaScript is exactly the same as EcmaScript, except that JavaScript includes some things (like window, document and navigator]) that are used in web browsers. If you've been writing JavaScript, you've been writing EcmaScript.
This chapter introduces how to work with strings and text in JavaScript. JavaScript's String type is used to represent textual data. It is a set of elements of 16-bit unsigned integer values. Each element in the String occupies a position in the String. The first element is at index 0, the next at index 1, and so on. The length of a String is the number of elements in it. You can create strings using string literals or string objects.
