Array in JS

Array

In JavaScript, an array is a special type of object used to store multiple values in a single variable. Arrays can hold any data type — numbers, strings, objects, or a mix. And Array can be determined as [].

How Array works ?

let tam = 81;                              
let eng = 87;                     const marks = [81,87,50,65,93];
let mat = 50;          =>                  
let sci = 65;       convert to
let soc = 93;         Array

Array Indexing

In JavaScript, indexing refers to accessing elements in indexed collections like arrays, strings, and typed arrays using a zero-based index.

• Arrays store elements in an ordered list.

• Index starts at 0 for the first element.

for example

const marks = [81,87,50,65,93];
for(let i=0;i<5;i++){
   console.log(marks[i]);
}

o/p - 81 87 50 65 93

1. Big Number

const marks = [81,87,50,65,93];
let big=marks[0];
for(let i=0;i<5;i++){
    if(marks[i]>big){
        big=marks[i];
    }
}
console.log(big);

o/p - 93

1. Small Number

const marks = [81,87,50,65,93];
let small=marks[0];
for(let i=0;i<5;i++){
    if(marks[i]<small){
        small=marks[i];
    }
}
console.log(small);

o/p - 50
