How to split a string into an array using javascript
str.split() function is used to split the given string into array of strings by separating it into substrings using a specified separator provided in the argument. The syntax of the function is as follows:
str.split(separator, limit)
Arguments
The first argument to this function is a string which specifies the points where the split has to take place. This argument can be treated as a simple string or as a regular expression. If the separator is unspecified then the entire string becomes one single array element. The same also happens when the separator is not present in the string. If the separator is an empty string (“”) then every character of the string is separated.
The second argument to the function limit defines the upper limit on the number of splits to be found in the given string. If the string remains unchecked after the limit is reached then it is not reported in the array.
Return value
This function returns an array of strings that is formed after splitting the given string at each point where the separator occurs.
Examples for the above function are provided below:
Example 1:
var str = 'It iS a 5r&e@@t Day.'
var array = str.split(" ");
print(array);
Output:
[It,iS,a,5r&e@@t,Day.]
In this example the function split() creates an array of strings by splitting str wherever ” “ occurs.
Example 2:
var str = 'It iS a 5r&e@@t Day.'
var array = str.split(" ",2);
print(array);
Output:
[It,iS]
In this example the function split() creates an array of strings by splitting str wherever ” “ occurs. The second argument 2 limits the number of such splits to only 2.
Codes for the above function are provided below:
