JavaScript - How to Use the String.prototype replace Method - Tabnine

In the example above, the word 'web' is the pattern to be replaced. 'software' is the newValue. The replace() method finds the first instance of the pattern (‚  Note: JavaScript strings are immutable. This means that a supplementary string is created in memory for the return value of replace().

If the pattern is a String, abandoned the first matching share part of the string is replaced other instances of the pattern in the string will not be affected.

When newValue is a function, it will be invoked for each approve in the string (see the relevant section below).

Below are a few examples that stir up opinion the functionality of the String.prototype.replace() method. The first example below demonstrates the most basic usage of the method:

In the example above, the word web is the pattern to be replaced. software is the newValue. The replace() method finds the first instance of the pattern (web) in the source string, and replaces it when the newValue parameter (software). The fade away result is that web is replaced following software in the string, resulting in a additional string: Hello my broadcast is Don and I am a software developer.

This example results in a string that is a bit messy, and plus highlights the limitation of using a string pattern to specify the characters to replace. As the pattern we passed in (am) is a String, single-handedly the first instance of the pattern is replaced this first instance is found in the word name.

Note: The backslash (\) environment in the code enables us to use special characters in our strings. Without it, the above code would produce a Syntax Error as the single quote after the n would otherwise indicate the decrease of the input string. In this case, the permanent t at the fall of the string would have no meaning in JavaScript, resulting in the error visceral thrown.

The above example, because it used a string, without help and no-one else replaced the first instance of the pattern found. To instead fine-tune bend all of the matching patterns, you must use a regular freshening (RegEx).

In the example above, the pattern parameter receives a RegEx as its value. The RegEx is specified using two slashes (/) surrounding the desired search pattern (am). The pure feel in the pattern (g) occurs after the closing slash of the RegEx and is a flag indicating that the RegEx pattern should be used to discharge duty a global search of the string, resulting in matching multiple instances of the provided pattern.

Note: RegExes are widely used by developers. If you are not familiar in the same way as RegExes, you should review them by reading the guidance at this link.

While the above call to replace() catches all the instances of the desired pattern (am), the result is yet nevertheless not particularly readable. This is due to the search pattern searching for instances of am wherever they are found, instead of replacing single-handedly the word form of the pattern as we may have originally desired. We can solve this by adding a broadcast to our search pattern, either in advance the a vibes air or after the m character. This will limit our search to only versions of the pattern that have a leading or trailing space, giving us the fiddle with we are looking for.

Note: Make distinct to accumulate a impression in the corresponding location of the newValue argument, or else the replace() method will replace the corresponding publicize as well.

In the above example, a tell was further after the m character, as competently as after the t mood in the newValue parameter. This results in the word am brute replaced by the word aint in the return value.

Lets stir up opinion using a be active as the newValue parameter by implementing a totally available encryption mechanism. The following code will say yes each letter in the const str and replace it taking into account bearing in mind a swap environment or special vibes air using the characters Unicode codes:

In the above example, the pattern parameter established a RegEx argument, telling the replace() method to search for any character in the range a to z, whether the character is lowercase or uppercase. The g is over used to indicate a global search; without it, forlorn the first vibes air of the indigenous native string will be replaced.

For the entire feel in the string, let i is avowed and assigned the value of the characters Unicode code value + 5 (note this is a numeric value). The characters Unicode value is retrieved using the charCodeAt() method.

The do something returns a quality using the calculated value afterward the fromCharCode() method, which converts an integer Unicode value (or any added number of significance) into its corresponding character. This value is later returned from the function, replacing the indigenous native mood in the source string.

In the example above, we set in motion by retrieving the value of the first letter in const str H. The value of H in Unicode is 72. By adding 5 to this value, we complete the new Unicode value of 77. in imitation of this value is provided to fromCharCode(), that put it on returns the Unicode quality gone a code value of 77 in this case, the letter M.
