xxxxxxxxxx
 
const text: string = 'This is some text...';
const array: string[] = text.split(' '); // space character separator used
​
console.log(array);

Output:

xxxxxxxxxx
 
['This', 'is', 'some', 'text...']

1.2. Split string by some text example

Edit

This section shows how to split string by some other string.

xxxxxxxxxx
 
const text: string = 'This is some text...';
const array: string[] = text.split('is'); // this character sequence separates string
​
console.log(array);

Output:

xxxxxxxxxx
 
['Th', ' ', ' some text...']

1.3. Split string to array of characters example

Edit

In this apprach empty string is used to split main string into array of characters.

xxxxxxxxxx
 
const text: string = 'This is some text...';
const array: string[] = text.split(''); // empty separator used
​
console.log(array);

Output:

xxxxxxxxxx
 
['T', 'h', 'i', 's', ' ', 'i', 's', ' ', 's', 'o', 'm', 'e', ' ', 't', 'e', 'x', 't', '.', '.', '.']

Note: this approach is strongly not recommended because of unicode characters that can be misinterpreted.

1.4. Split string by space with result size limit example

Edit

This section shows how to split string by space limiting output array size to two elements.

xxxxxxxxxx
 
const text: string = 'This is some text...';
const array: string[] = text.split(' ', 2); // maximum result array size will be 2
​
console.log(array);

Output:

xxxxxxxxxx
 
['This', 'is']

2. Split string with regex (regular expression)

Edit

Each string can be splitted in TypeScript with regular expresion.

2.1. Split string by white character symbol example

Edit

In this example white character symbol is used to spltit text to single words.

xxxxxxxxxx
 
const text: string = 'This is some text...';
const array: string[] = text.split(/\b/); // begin or end of word separates string
​
console.log(array);

Output:

xxxxxxxxxx
 
['This', ' ', 'is', ' ', 'some', ' ', 'text', '...']

2.2. Split string by white character symbol with result size limit example

Edit

In this example white character symbol is used to spltit text to single words limiting output array size to two elements.

xxxxxxxxxx
 
const text: string = 'This is some text...';
const array: string[] = text.split(/\b/, 2); // maximum result array size will be 2
​
console.log(array);

Output:

xxxxxxxxxx
 
['This', ' ']
